Clinical tests of materials and designs are crucial to prove the accuracy and validate such measurements. The purpose of this study is to examine the affection of THA gait kinematics and kinetics on wear during gait, the essential functional activity of humans, by comparing in vivo gait data to in vitro results. Our study hypothesis is that both implants will present the same hip joint kinematics and kinetics during gait. 127 unilateral primary cementless total hip arthroplasties were included in the research. Independent t-tests were used to identify a statistically significant difference in kinetic and kinematic data extracted from 3D gait analysis. No statistically significant differences observed at mean peak abduction, flexion and extension moments between the two groups (P.abduction= 0,125, P.flexion= 0,218, P.extension= 0,082). The kinematic measurements show no statistically significant differences too (Prom flexion-extension= 0,687, Prom abduction-adduction= 0,679). THA kinematics and kinetics during gait are important biomechanical parameters directly associated with implants wear. In vitro studies report less wear in CoC than CoXLPE when tested with the same gait cycle kinematic protocol. Our findings confirm that both implants behave identically in terms of kinematics in the clinical environment, thus strengthening in vitro results of CoC advantage. Correlated to all other significant factors that affect THA wear could address in a complete prism the wear on CoC and CoXLPE. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=total%20hip%20arthroplasty%20biomechanics" title="total hip arthroplasty biomechanics">total hip arthroplasty biomechanics</a>, <a href="https://publications.waset.org/abstracts/search?q=THA%20gait%20analysis" title=" THA gait analysis"> THA gait analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=ceramic%20on%20ceramic%20kinematics" title=" ceramic on ceramic kinematics"> ceramic on ceramic kinematics</a>, <a href="https://publications.waset.org/abstracts/search?q=ceramic%20on%20XLPE%20kinetics" title=" ceramic on XLPE kinetics"> ceramic on XLPE kinetics</a>, <a href="https://publications.waset.org/abstracts/search?q=total%20hip%20replacement%20wear" title=" total hip replacement wear"> total hip replacement wear</a> </p> <a href="https://publications.waset.org/abstracts/142806/biomechanics-of-ceramic-on-ceramic-vs-ceramic-on-xlpe-total-hip-arthroplasties-during-gait" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/142806.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">154</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">10015</span> Dry Sliding Wear Behaviour of Ti3SiC2 and the Effect of TiC on Its</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Bendaoudi%20Seif-Eddine">Bendaoudi Seif-Eddine</a>, <a href="https://publications.waset.org/abstracts/search?q=Bounazef%20Mokhtar"> Bounazef Mokhtar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Wear behaviour of Ti3SiC2 coating in contact sliding under dry condition have been investigated on different pressures (0.1-0.8 MPa) at various speeds from 5 to 60 m/s.

An equation has been proposed to predict wear rates and describe sliding wear caused by Corundum ball on the studied material. The results show how the wear rate, measured by mass loss, varies in the range of (0.6 – 3.8 x E-6 mm3/Nm) with normal sliding distance under various test conditions; it increases with increasing load and rapidly with speed.

Although different material combinations are used for these joints, biopolymers are most commonly preferred materials especially for acetabular cup and tibial component of hip and knee joints respectively. The main limitation that shortens the service life of these prostheses is wear. Wear is complicated phenomena and it must be considered with friction and lubrication. In this study, micro wave (MW) induced argon+oxygen plasma surface modification were applied on ultra-high molecular weight polyethylene (UHMWPE) and vitamin E blended UHMWPE (VE-UHMWPE) biopolymer surfaces to improve surface wettability and wear resistance of the surfaces. Contact angel measurement method was used for determination of wettability. Ball-on-disc wear test was applied under 25% bovine serum lubrication conditions. The results show that surface wettability and wear resistance of both material samples were increased by plasma surface modification. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=artificial%20joints" title="artificial joints">artificial joints</a>, <a href="https://publications.waset.org/abstracts/search?q=plasma%20surface%20modification" title=" plasma surface modification"> plasma surface modification</a>, <a href="https://publications.waset.org/abstracts/search?q=UHMWPE" title=" UHMWPE"> UHMWPE</a>, <a href="https://publications.waset.org/abstracts/search?q=vitamin%20E" title=" vitamin E"> vitamin E</a>, <a href="https://publications.waset.org/abstracts/search?q=wear" title=" wear"> wear</a> </p> <a href="https://publications.waset.org/abstracts/50095/argonoxygen-plasma-surface-modification-of-biopolymers-for-improvement-of-wettability-and-wear-resistance" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/50095.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">306</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">10013</span> Comparisons of Individual and Group Replacement Policies for a Series Connection System with Two Machines</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Wen%20Liang%20Chang">Wen Liang Chang</a>, <a href="https://publications.waset.org/abstracts/search?q=Mei%20Wei%20Wang"> Mei Wei Wang</a>, <a href="https://publications.waset.org/abstracts/search?q=Ruey%20Huei%20Yeh"> Ruey Huei Yeh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper studies the comparisons of individual and group replacement policies for a series connection system with two machines. Suppose that manufacturer’s production system is a series connection system which is combined by two machines. For two machines, when machines fail within the operating time, minimal repair is performed for machines by the manufacturer. The manufacturer plans to a preventive replacement for machines at a pre-specified time to maintain system normal operation. Under these maintenance policies, the maintenance cost rate models of individual and group replacement for a series connection system with two machines is derived and further, optimal preventive replacement time is obtained such that the expected total maintenance cost rate is minimized.

The clay soil was replaced with 0%, 10%, 20% to 100% A-3 soil, compacted at both the BSL and BSH compaction energy level and using unconfined compressive strength as evaluation criteria. The MDD of the compactions at both the BSL and BSH compaction energy levels showed increase in MDD from 0% A-3 soil replacement to 40% A-3 soil replacement after which the values reduced to 100% A-3 soil replacement. The trend of the OMC with varied A-3 soil replacement is similar to that of MDD but in a reversed order. The OMC reduced from 0% A-3 soil replacement to 40% A-3 soil replacement after which the values increased to 100% A-3 soil replacement. This trend was attributed to the observed reduction in the void ratio from 0% A-3 soil replacement to 40% A-3 soil replacement after which the void ratio increased to 100% A-3 soil replacement. The maximum UCS for clay at varied A-3 soil replacement increased from 272 and 770kN/m2 for BSL and BSH compaction energy level at 0% A-3 soil replacement to 295 and 795kN/m2 for BSL and BSH compaction energy level respectively at 10% A-3 soil replacement after which the values reduced to 22 and 60kN/m2 for BSL and BSH compaction energy level respectively at 70% A-3 soil replacement. Beyond 70% A-3 soil replacement, the mixture cannot be moulded for UCS test. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=A-3%20soil" title="A-3 soil">A-3 soil</a>, <a href="https://publications.waset.org/abstracts/search?q=clay%20minerals" title=" clay minerals"> clay minerals</a>, <a href="https://publications.waset.org/abstracts/search?q=pozzolanic%20action" title=" pozzolanic action"> pozzolanic action</a>, <a href="https://publications.waset.org/abstracts/search?q=stabilization" title=" stabilization"> stabilization</a> </p> <a href="https://publications.waset.org/abstracts/33993/stabilization-of-clay-soil-using-a-3-soil" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/33993.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">444</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">10010</span> Gear Wear Product Analysis as Applied for Tribological Maintenance Diagnostics</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Surapol%20Raadnui">Surapol Raadnui</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper describes an experimental investigation on a pair of gears in which wear and pitting were intentionally allowed to occur, namely, moisture corrosion pitting, acid-induced corrosion pitting, hard contaminant-related pitting and mechanical induced wear.

Experiments were conducted with varying sliding distance from 0.2 km to 4.6 km, wherein the sliding velocity was kept constant, 0.64 ms<sup>-1</sup>. The results reveal that the weight loss increases with applied load and the sliding distance. The nature of the wear rate was very similar in both the sliding environments in which initially the wear rate increased very rapidly with increasing sliding distance and then progressed to a slower rate. Moreover, the wear rate in wet sliding environment was significantly lower than that under dry sliding condition. The worn surfaces were characterized by optical microscope and SEM.

Thus, it should be possible to detect and diagnose gear pitting and wear utilization of worn surfaces, generated wear debris and quantitative measurement such as weight loss. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=predictive%20maintenance" title="predictive maintenance">predictive maintenance</a>, <a href="https://publications.waset.org/abstracts/search?q=worm%20gear" title=" worm gear"> worm gear</a>, <a href="https://publications.waset.org/abstracts/search?q=spur%20gear" title=" spur gear"> spur gear</a>, <a href="https://publications.waset.org/abstracts/search?q=wear%20debris%20analysis" title=" wear debris analysis"> wear debris analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=problem%20diagnostic" title=" problem diagnostic"> problem diagnostic</a> </p> <a href="https://publications.waset.org/abstracts/140861/wear-particle-analysis-from-used-gear-lubricants-for-maintenance-diagnostics" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/140861.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">153</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">10007</span> Design and Development of Engine Valve Train Wear Test Rig for the Assessment of Valve Train Tribochemistry</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=V.%20Manjunath">V.

From this viewpoint, engine manufacturers require the optimum combination of materials and lubricant additive package to minimize friction and wear in the engine components like piston, crankshaft and valve train etc. The demands are placed for requirements to operate at higher speeds, loads, temperature and for extended replacement intervals of engine oil. Besides, it is necessary to accurately predict the lubricant life or the replacement interval to prevent lubrication and valve-train components failure. Experimental tribology evaluation of new engine oils requires large amount of time and energy. Hence low cost bench test is necessary for industries and original equipment manufacturing companies (OEM) to study the performance of lubricants. The present work outlines the procedure for the design and development of a valve train wear rig (MCR) to simulate the ASTMD-6891 and to develop new engine test for Indian automobile sector to evaluate lubricants for Indian automobile market. In order to improve the lubrication between cam and follower of internal combustion engine, the influence of materials or oils viscosity and additives on the friction and wear characteristics are examined with test rig by increasing the contact load at two different revolution speed. From the experimentation following results are made obvious. Temperature, Torque, speed and wear plots are used to validate the data obtained from the newly developed multi-cam cam rig (MCR) with follower against a cast iron camshaft. Camshaft lobe wear is measured at seven different locations on cam profile. Tribofilm formed using 5W-30 oil is evaluated and correlated with the standard test results. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ASTMD-6891" title="ASTMD-6891">ASTMD-6891</a>, <a href="https://publications.waset.org/abstracts/search?q=multi-cam%20rig%20%28MCR%29" title=" multi-cam rig (MCR)"> multi-cam rig (MCR)</a>, <a href="https://publications.waset.org/abstracts/search?q=5W-30" title=" 5W-30"> 5W-30</a>, <a href="https://publications.waset.org/abstracts/search?q=cam-profile" title=" cam-profile"> cam-profile</a> </p> <a href="https://publications.waset.org/abstracts/73458/design-and-development-of-engine-valve-train-wear-test-rig-for-the-assessment-of-valve-train-tribochemistry" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/73458.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">176</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">10006</span> To Study the Effect of Optic Fibre Laser Cladding of Cast Iron with Silicon Carbide on Wear Rate</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kshitij%20Sawke">Kshitij Sawke</a>, <a href="https://publications.waset.org/abstracts/search?q=Pradnyavant%20Kamble"> Pradnyavant Kamble</a>, <a href="https://publications.waset.org/abstracts/search?q=Shrikant%20Patil"> Shrikant Patil</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The study investigates the effect on wear rate of laser clad of cast iron with silicon carbide.

However, relatively very less work has been done related to the wear behavior of these composites. Magnesium matrix composites have wide applications in automobile and aerospace sector. In this review, attempt has been done to collect the literature related to wear behavior of magnesium matrix composites fabricated through various processing techniques such as stir casting, powder metallurgy, friction stir processing etc. Effect of different reinforcements, reinforcement content, reinforcement size, wear load, sliding speed and time have been studied by different researchers in detail. Wear mechanism under different experimental condition has been reviewed in detail. The wear resistance of magnesium and its alloys can be enhanced with the addition of different reinforcements. Wear resistance can further be enhanced by increasing the percentage of added reinforcements. Increase in applied load during wear test leads to increase in wear rate of magnesium composites. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=hardness" title="hardness">hardness</a>, <a href="https://publications.waset.org/abstracts/search?q=magnesium%20matrix%20composites" title=" magnesium matrix composites"> magnesium matrix composites</a>, <a href="https://publications.waset.org/abstracts/search?q=reinforcement" title=" reinforcement"> reinforcement</a>, <a href="https://publications.waset.org/abstracts/search?q=wear" title=" wear"> wear</a> </p> <a href="https://publications.waset.org/abstracts/52187/review-on-wear-behavior-of-magnesium-matrix-composites" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/52187.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">332</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">10004</span> The Influence of Cycle Index of Simulation Condition on Main Bearing Wear Prognosis of Internal Combustion Engine</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ziyu%20Diao">Ziyu Diao</a>, <a href="https://publications.waset.org/abstracts/search?q=Yanyan%20Zhang"> Yanyan Zhang</a>, <a href="https://publications.waset.org/abstracts/search?q=Zhentao%20Liu"> Zhentao Liu</a>, <a href="https://publications.waset.org/abstracts/search?q=Ruidong%20Yan"> Ruidong Yan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The update frequency of wear profile in main bearing wear prognosis of internal combustion engine plays an important role in the calculation efficiency and accuracy. In order to investigate the appropriate cycle index of the simplified working condition of wear simulation, the main bearing-crankshaft journal friction pair of a diesel engine in service was studied in this paper. The method of multi-body dynamics simulation was used, and the wear prognosis model of the main bearing was established. Several groups of cycle indexes were set up for the wear calculation, and the maximum wear depth and wear profile were compared and analyzed. The results showed that when the cycle index reaches 3, the maximum deviation rate of the maximum wear depth is about 2.8%, and the maximum deviation rate comes to 1.6% when the cycle index reaches 5.

It is found that the wear behavior of SLS glass in humid air is very sensitive to the water and SO₂ treatment environments based on the wear test using a ball-on-flat reciprocation tribometer. When SLS glass is treated with SO₂-without, the presence of water, the wear resistance of SLS glass in humid air becomes significantly higher compared to the pristine glass. However, when SLS glass is treated with SO₂ with the presence of water, the wear resistance of SLS glass decreases remarkably with increasing in the relative humidity (RH) from 0% to 90%. Further analyses indicate that when sodium ions are leached out of SLS glass surface via the water and SO₂ treatments, the mechanochemical properties of SLS glass surface become different depending on the RH. At lower humidity, the nano hardness of the Na⁺-leached surface is higher, and it can contribute to the enhanced wear resistance of SLS glass. In contrast, at higher humidity conditions, the SLS glass surface is more hydrophilic, and substantial wear debris can be found inside the wear track of SLS glass. Those phenomena suggest that adhesive wear and abrasive wear dominate the wear mechanism of SLS glass in humid air, causing the decreased wear resistance of SLS glass with increasing the RH. These results may not only provide a deep understanding of the wear mechanism of SLS glass but also helpful for operation process of functional and engineering glasses. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=soda%20lime%20silicate%20glass" title="soda lime silicate glass">soda lime silicate glass</a>, <a href="https://publications.waset.org/abstracts/search?q=wear" title=" wear"> wear</a>, <a href="https://publications.waset.org/abstracts/search?q=water" title=" water"> water</a>, <a href="https://publications.waset.org/abstracts/search?q=SO%E2%82%82" title=" SO₂"> SO₂</a> </p> <a href="https://publications.waset.org/abstracts/115431/synergetic-effects-of-water-and-sulfur-dioxide-treatments-on-wear-of-soda-lime-silicate-glass" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/115431.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">176</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">10002</span> Wear Measuring and Wear Modelling Based On Archard, ASTM, and Neural Network Models</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=A.%20Shebani">A.

The prediction of wear is a fundamental problem in the industrial field, mainly correlated to the planning of maintenance interventions and economy. Pin-on-disc test is the most common test which is used to study the wear behaviour. In this paper, the pin-on-disc (AEROTECH UNIDEX 11) is used for the investigation of the effects of normal load and hardness of material on the wear under dry and sliding conditions. In the pin-on-disc rig, two specimens were used; one, a pin which is made of steel with a tip, is positioned perpendicular to the disc, where the disc is made of aluminium. The pin wear and disc wear were measured by using the following instruments: The Talysurf instrument, a digital microscope, and the alicona instrument; where the Talysurf profilometer was used to measure the pin/disc wear scar depth, and the alicona was used to measure the volume loss for pin and disc. After that, the Archard model, American Society for Testing and Materials model (ASTM), and neural network model were used for pin/disc wear modelling and the simulation results are implemented by using the Matlab program. This paper focuses on how the alicona can be considered as a powerful tool for wear measurements and how the neural network is an effective algorithm for wear estimation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=wear%20modelling" title="wear modelling">wear modelling</a>, <a href="https://publications.waset.org/abstracts/search?q=Archard%20Model" title=" Archard Model"> Archard Model</a>, <a href="https://publications.waset.org/abstracts/search?q=ASTM%20Model" title=" ASTM Model"> ASTM Model</a>, <a href="https://publications.waset.org/abstracts/search?q=Neural%20Networks%20Model" title=" Neural Networks Model"> Neural Networks Model</a>, <a href="https://publications.waset.org/abstracts/search?q=Pin-on-disc%20Test" title=" Pin-on-disc Test"> Pin-on-disc Test</a>, <a href="https://publications.waset.org/abstracts/search?q=Talysurf" title=" Talysurf"> Talysurf</a>, <a href="https://publications.waset.org/abstracts/search?q=digital%20microscope" title=" digital microscope"> digital microscope</a>, <a href="https://publications.waset.org/abstracts/search?q=Alicona" title=" Alicona "> Alicona </a> </p> <a href="https://publications.waset.org/abstracts/17801/wear-measuring-and-wear-modelling-based-on-archard-astm-and-neural-network-models" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/17801.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">456</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">10001</span> The Effect of Surface Conditions on Wear of a Railway Wheel and Rail</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=A.%20Shebani">A.

Twin disc wear testing is used extensively for studying wear of wheel and rail materials. The University of Huddersfield twin disc rig was used in this paper to examine the effect of surface conditions on wheel and rail wear measurement under a range of wheel/rail contact conditions, with and without contaminants. This work focuses on an investigation of the effect of dry, wet, and lubricated conditions and the effect of contaminants such as sand on wheel and rail wear. The wheel and rail wear measurements were carried out by using a replica material and an optical profilometer that allows measurement of wear in difficult location with high accuracy. The results have demonstrated the rate at which both water and oil reduce wheel and rail wear. Scratches and other damage were seen on the wheel and rail surfaces after the addition of sand and consequently both wheel and rail wear damage rates increased under these conditions. This work introduced the replica material and an optical instrument as effective tools to study the effect of surface conditions on wheel and rail wear. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=railway%20wheel%2Frail%20wear" title="railway wheel/rail wear">railway wheel/rail wear</a>, <a href="https://publications.waset.org/abstracts/search?q=surface%20conditions" title=" surface conditions"> surface conditions</a>, <a href="https://publications.waset.org/abstracts/search?q=twin%20disc%20test%20rig" title=" twin disc test rig"> twin disc test rig</a>, <a href="https://publications.waset.org/abstracts/search?q=replica%20material" title=" replica material"> replica material</a>, <a href="https://publications.waset.org/abstracts/search?q=Alicona%20profilometer" title=" Alicona profilometer"> Alicona profilometer</a> </p> <a href="https://publications.waset.org/abstracts/47795/the-effect-of-surface-conditions-on-wear-of-a-railway-wheel-and-rail" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/47795.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">352</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">10000</span> Wear Resistance of 20MnCr5 Steel Nitrided by Plasma</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Okba%20Belahssen">Okba Belahssen</a>, <a href="https://publications.waset.org/abstracts/search?q=Said%20Benramache"> Said Benramache</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper presents wear behavior of the plasma-nitrided 20MnCr5 steel.

Researchers are keen to find the solution for copper-free FMs by using different metals or without metals. Steel wool is used as a reinforcement in non-asbestos organic (NAO) FMs mainly for increasing thermal conductivity, and it affects wear adversely, most of the times and also adds friction fluctuations. Copper and brass used to be the preferred choices because of superior performance in almost every aspect except cost. Since these are being phased out because of a proven threat to the aquatic life. Keeping this in view, a series of realistic multi-ingredient FMs containing stainless steel (SS) swarfs as a theme ingredient in increasing amount (0, 5, 10 and 15 wt. %- S₅, S₁₀, and S₁₅) were developed in the form of brake-pads. One more composite containing copper instead of SS swarfs (C₁₀) was developed. These composites were characterized for physical, mechanical, chemical and tribological performance. Composites were tribo-evaluated on a chase machine with various test loops as per SAE J661 standards. Various performance parameters such as normal µ, hot µ, performance µ, fade µ, recovery µ, % fade, % recovery, wear resistance, etc. were used to evaluate the role of amount of SS swarfs in FMs. It was concluded that SS swarfs proved successful in Cu replacement almost in all respects except wear resistance. With increase in amount of SS swarfs, most of the properties improved. Worn surface analysis and wear mechanism were studied using SEM and EDAX techniques. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Chase%20type%20friction%20tester" title="Chase type friction tester">Chase type friction tester</a>, <a href="https://publications.waset.org/abstracts/search?q=copper-free" title=" copper-free"> copper-free</a>, <a href="https://publications.waset.org/abstracts/search?q=non-asbestos%20organic%20%28NAO%29%20friction%20materials" title=" non-asbestos organic (NAO) friction materials"> non-asbestos organic (NAO) friction materials</a>, <a href="https://publications.waset.org/abstracts/search?q=stainless%20steel%20swarfs" title=" stainless steel swarfs"> stainless steel swarfs</a> </p> <a href="https://publications.waset.org/abstracts/80071/stainless-steel-swarfs-for-replacement-of-copper-in-non-asbestos-organic-brake-pads" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/80071.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">181</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">9998</span> A Review of Fractal Dimension Computing Methods Applied to Wear Particles</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Manish%20Kumar%20Thakur">Manish Kumar Thakur</a>, <a href="https://publications.waset.org/abstracts/search?q=Subrata%20Kumar%20Ghosh"> Subrata Kumar Ghosh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Various types of particles found in lubricant may be characterized by their fractal dimension. Some of the available methods are: yard-stick method or structured walk method, box-counting method. This paper presents a review of the developments and progress in fractal dimension computing methods as applied to characteristics the surface of wear particles. An overview of these methods, their implementation, their advantages and their limits is also present here. It has been accepted that wear particles contain major information about wear and friction of materials. Morphological analysis of wear particles from a lubricant is a very effective way for machine condition monitoring. Fractal dimension methods are used to characterize the morphology of the found particles. It is very useful in the analysis of complexity of irregular substance. The aim of this review is to bring together the fractal methods applicable for wear particles. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=fractal%20dimension" title="fractal dimension">fractal dimension</a>, <a href="https://publications.waset.org/abstracts/search?q=morphological%20analysis" title=" morphological analysis"> morphological analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=wear" title=" wear"> wear</a>, <a href="https://publications.waset.org/abstracts/search?q=wear%20particles" title=" wear particles"> wear particles</a> </p> <a href="https://publications.waset.org/abstracts/48239/a-review-of-fractal-dimension-computing-methods-applied-to-wear-particles" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/48239.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">490</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">9997</span> Predictive Modeling of Flank Wear in Hard Turning Using the Taguchi Method</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Suha%20K.%20Shihab">Suha K.

Nine experiments were performed based on Taguchi’s L9 orthogonal array. Analysis of variance (ANOVA) was used to determine the effects of the cutting parameters on flank wear. The results of the study revealed that the cutting speed (A) and feed rate (B) are the dominant factors affecting flank wear, while the depth of cut (C) has not a significant effect. The optimal combination of the cutting parameters for flank wear is found to be A1B1C1. The mathematical model for flank wear is found to be statistically significant. The predicted and measured values of flank wear are found to be very close to each other. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=flank%20wear" title="flank wear">flank wear</a>, <a href="https://publications.waset.org/abstracts/search?q=hard%20turning" title=" hard turning"> hard turning</a>, <a href="https://publications.waset.org/abstracts/search?q=Taguchi%20approach" title=" Taguchi approach"> Taguchi approach</a>, <a href="https://publications.waset.org/abstracts/search?q=optimization" title=" optimization "> optimization </a> </p> <a href="https://publications.waset.org/abstracts/7473/predictive-modeling-of-flank-wear-in-hard-turning-using-the-taguchi-method" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/7473.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">664</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">9996</span> Computational Study and Wear Prediction of Steam Turbine Blade with Titanium-Nitride Coating Deposited by Physical Vapor Deposition Method</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Karuna%20Tuchinda">Karuna Tuchinda</a>, <a href="https://publications.waset.org/abstracts/search?q=Sasithon%20Bland"> Sasithon Bland</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This work investigates the wear of a steam turbine blade coated with titanium nitride (TiN), and compares to the wear of uncoated blades.

This data was used in the finite element wear model developed here in order to predict the wear of the blade. The wear mechanisms considered are erosive wear due to particle impingement and fluid jet, and fatigue wear due to repeated impingement of particles and fluid jet.

Since efficient operation of AGVs is critical for the productivity of the container terminal, the replacement of batteries of the AGVs must be conducted in a strategic way to minimize undesirable transportation interruptions. While a too frequent replacement may lead to a loss of terminal productivity by delaying container deliveries, missing the right timing of battery replacement can result in a dead AGV that causes a severer productivity loss due to the extra efforts required to finish post treatment. In this paper, we propose a strategy for battery replacement based on a scoring function of multiple criteria taking into account the current battery level, the distances to different battery stations, and the progress of the terminal job operations. The strategy is optimized using a genetic algorithm with the objectives of minimizing the total time spent for battery replacement as well as maximizing the terminal productivity. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=AGV%20operation" title="AGV operation">AGV operation</a>, <a href="https://publications.waset.org/abstracts/search?q=automated%20container%20terminal" title=" automated container terminal"> automated container terminal</a>, <a href="https://publications.waset.org/abstracts/search?q=battery%20replacement" title=" battery replacement"> battery replacement</a>, <a href="https://publications.waset.org/abstracts/search?q=electric%20AGV" title=" electric AGV"> electric AGV</a>, <a href="https://publications.waset.org/abstracts/search?q=strategy%20optimization" title=" strategy optimization"> strategy optimization</a> </p> <a href="https://publications.waset.org/abstracts/43477/battery-replacement-strategy-for-electric-agvs-in-an-automated-container-terminal" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/43477.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">388</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">9994</span> Comparison of the Effect of Feldspathic Porcelain and Zirconia on Natural Tooth Wear</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ammar%20Neshati">Ammar Neshati</a>, <a href="https://publications.waset.org/abstracts/search?q=Elham%20Hamidi%20Shishavan"> Elham Hamidi Shishavan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background and Aim: Enamel wear is among the main disadvantages of ceramic restorations. Recently, use of full zirconia crowns without dental porcelain has been suggested. The aim of this study was to compare the effect of feldspathic porcelain and zirconia on the wear of natural teeth. Materials and Methods: In this experimental study, 22 zirconia specimens were fabricated; out of which, 11 specimens were polished and used as zirconia specimens while the remaining 11 were used to fabricate porcelain specimens. A total of 22 natural human teeth were also collected. The natural teeth were photographed by a stereomicroscope in a fixed position and the distance from the cusp tip to a reference point was measured. Next, 11 teeth opposed zirconia and the remaining 11 opposed porcelain specimens in a chewing simulator and subjected to 120,000 masticatory cycles. The teeth were photographed again and the greatest difference between the before and after values was recorded. Results: The mean (± standard deviation) wear rate was 153.8±95.68 and 306.3±127.74, in the zirconia and porcelain groups, respectively; and the two groups had a statistically significant difference in this respect (P=0.007). Conclusion: The mean wear was significantly lower in teeth opposing zirconia than in those opposing feldspathic porcelain. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=natural%20tooth%20wear" title="natural tooth wear">natural tooth wear</a>, <a href="https://publications.waset.org/abstracts/search?q=feldspathic%20porcelain" title=" feldspathic porcelain"> feldspathic porcelain</a>, <a href="https://publications.waset.org/abstracts/search?q=zirconia" title=" zirconia"> zirconia</a>, <a href="https://publications.waset.org/abstracts/search?q=effect" title=" effect"> effect</a> </p> <a href="https://publications.waset.org/abstracts/20316/comparison-of-the-effect-of-feldspathic-porcelain-and-zirconia-on-natural-tooth-wear" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/20316.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">402</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">9993</span> Neural Network Monitoring Strategy of Cutting Tool Wear of Horizontal High Speed Milling</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kious%20Mecheri">Kious Mecheri</a>, <a href="https://publications.waset.org/abstracts/search?q=Hadjadj%20Abdechafik"> Hadjadj Abdechafik</a>, <a href="https://publications.waset.org/abstracts/search?q=Ameur%20Aissa"> Ameur Aissa</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The wear of cutting tool degrades the quality of the product in the manufacturing processes. The online monitoring of the cutting tool wear level is very necessary to prevent the deterioration of the quality of machining. Unfortunately there is not a direct manner to measure the cutting tool wear online. Consequently we must adopt an indirect method where wear will be estimated from the measurement of one or more physical parameters appearing during the machining process such as the cutting force, the vibrations, or the acoustic emission etc. In this work, a neural network system is elaborated in order to estimate the flank wear from the cutting force measurement and the cutting conditions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=flank%20wear" title="flank wear">flank wear</a>, <a href="https://publications.waset.org/abstracts/search?q=cutting%20forces" title=" cutting forces"> cutting forces</a>, <a href="https://publications.waset.org/abstracts/search?q=high%20speed%20milling" title=" high speed milling"> high speed milling</a>, <a href="https://publications.waset.org/abstracts/search?q=signal%20processing" title=" signal processing"> signal processing</a>, <a href="https://publications.waset.org/abstracts/search?q=neural%20network" title=" neural network"> neural network</a> </p> <a href="https://publications.waset.org/abstracts/6906/neural-network-monitoring-strategy-of-cutting-tool-wear-of-horizontal-high-speed-milling" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/6906.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">393</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">9992</span> A Review of Tribological Excellence of Bronze Alloys</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ram%20Dhani%20chauhan">Ram Dhani chauhan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Tribology is a term that was developed from the Greek words ‘tribos’ (rubbing) and ‘logy’ (knowledge). In other words, a study of wear, friction and lubrication of material is known as Tribology. In groundwater irrigation, the life of submersible pump components like impeller, bush and wear ring will depend upon the wear and corrosion resistance of casted material. Leaded tin bronze (LTB) is an easily castable material with good mechanical properties and tribological behaviour and is utilised in submersible pumps at large. It has been investigated that, as Sn content increases from 4-8 wt. % in LTB alloys, the hardness of the alloys increases and the wear rate decreases. Similarly, a composite of copper with 3% wt. Graphite (threshold limit of mix) has a lower COF (coefficient of friction) and the lowest wear rate. In LTB alloys, in the initial low-speed range, wear increases and in the higher range, it was found that wear rate decreases. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=coefficent%20of%20friction" title="coefficent of friction">coefficent of friction</a>, <a href="https://publications.waset.org/abstracts/search?q=coefficient%20of%20wear" title=" coefficient of wear"> coefficient of wear</a>, <a href="https://publications.waset.org/abstracts/search?q=tribology" title=" tribology"> tribology</a>, <a href="https://publications.waset.org/abstracts/search?q=leaded%20tin%20bronze" title=" leaded tin bronze"> leaded tin bronze</a> </p> <a href="https://publications.waset.org/abstracts/192235/a-review-of-tribological-excellence-of-bronze-alloys" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/192235.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">19</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">9991</span> Tribological Study of TiC Powder Cladding on 6061 Aluminum Alloy</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yuan-Ching%20Lin">Yuan-Ching Lin</a>, <a href="https://publications.waset.org/abstracts/search?q=Sin-Yu%20Chen"> Sin-Yu Chen</a>, <a href="https://publications.waset.org/abstracts/search?q=Pei-Yu%20Wu"> Pei-Yu Wu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study reports the improvement in the wear performance of A6061 aluminum alloy clad with mixed powders of titanium carbide (TiC), copper (Cu) and aluminum (Al) using the gas tungsten arc welding (GTAW) method. The wear performance of the A6061 clad layers was evaluated by performing pin-on-disc mode wear test. Experimental results clearly indicate an enhancement in the hardness of the clad layer by about two times that of the A6061 substrate without cladding. Wear test demonstrated a significant improvement in the wear performance of the clad layer when compared with the A6061 substrate without cladding. Moreover, the interface between the clad layer and the A6061 substrate exhibited superior metallurgical bonding. Due to this bonding, the clad layer did not spall during the wear test; as such, massive wear loss was prevented. Additionally, massive oxidized particulate debris was generated on the worn surface during the wear test; this resulted in three-body abrasive wear and reduced the wear behavior of the clad surface. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=GTAW%E3%80%81A6061%20aluminum%20alloy" title="GTAW、A6061 aluminum alloy">GTAW、A6061 aluminum alloy</a>, <a href="https://publications.waset.org/abstracts/search?q=%E3%80%81surface%20modification" title="、surface modification">、surface modification</a>, <a href="https://publications.waset.org/abstracts/search?q=tribological%20study" title=" tribological study"> tribological study</a>, <a href="https://publications.waset.org/abstracts/search?q=TiC%20powder%20cladding" title=" TiC powder cladding"> TiC powder cladding</a> </p> <a href="https://publications.waset.org/abstracts/25409/tribological-study-of-tic-powder-cladding-on-6061-aluminum-alloy" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/25409.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">463</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">9990</span> Solution for Rider Ring Wear Problem in Boil off Gas Reciprocating Compressor: A Case Study</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hessam%20Mortezaei">Hessam Mortezaei</a>, <a href="https://publications.waset.org/abstracts/search?q=Saeid%20Joudakian"> Saeid Joudakian</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, the wear problem on rider rings of boil off gas compressor has been studied.

Considering the diversity of the working conditions of brake system, it is necessary to identify well and understand the tribological performance and wear mechanisms of friction materials for different conditions. Fe has been a preferred reinforcement for copper-based friction materials, due to its ability to improve the wear resistance and mechanical properties of material. Wear map is well accepted as a useful research method for evaluation of wear performances and wear mechanisms over a wider range of working conditions. Therefore, it is significantly important to construct a wear map which can give out the effects of work condition and Fe reinforcement on tribological performance of Cu-based friction materials. In this study, the copper-based sintered friction materials with the different addition of Fe reinforcement (0-20 vol. %) were studied. The tribological tests were performed against stainless steel in a ring-on-ring braking tester with varying braking energy density (0-5000 J/cm2). The linear wear and friction coefficient were measured. The worn surface, cross section and debris were analyzed to determine the dominant wear mechanisms for different testing conditions. On the basis of experimental results, the wear map and wear mechanism map were established, in terms of braking energy density and the addition of Fe. It was found that with low contents of Fe and low braking energy density, adhesive wear was the dominant wear mechanism of friction materials. Oxidative wear and abrasive wear mainly occurred under moderate braking energy density. In the condition of high braking energy density, with both high and low addition of Fe, delamination appeared as the main wear mechanism. <p class="card-text"><strong>Keywords:</strong> <a
