A heat treatment and then surface coating can have a large effect on erosion damage. Samples have been tested to evaluate their resistances to erosive wear and to assess how this compares with behaviour seen for untreated material. Five commercial (PN + TiN), (PN + TiAlCN), (TiN X 2), (TiN), and (TiAlCN) coatings have been evaluated for their wear resistance. The objective was to permit an optimized selection of coatings to be used to give good resistance to erosive wear. A test-Rig has been developed to study the erosive wear in aluminium die casting and provide an environment similar to industrial operation that is more practical than using actual machines. These surfaces were analysed using a Scanning Electron Microscope (SEM) and Optical Microscopes each with a different level of resolution. Examination of coating materials revealed an important parameter associated with the failure of the coating materials.This was adhesion of the coating material to the substrate surface. A well-adhered coating withstands wear much better compared to the poorest-adhering coating. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=solid%20particle%20erosion" title="solid particle erosion">solid particle erosion</a>, <a href="https://publications.waset.org/abstracts/search?q=PVD-coatings" title=" PVD-coatings"> PVD-coatings</a>, <a href="https://publications.waset.org/abstracts/search?q=steel" title=" steel"> steel</a>, <a href="https://publications.waset.org/abstracts/search?q=erosion%20testing" title=" erosion testing"> erosion testing</a> </p> <a href="https://publications.waset.org/abstracts/31573/evaluation-of-erosive-wear-resistance-of-commercial-hard-coatings-with-plasma-nitride-and-without-plasma-nitride-in-aluminium-die-casting" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/31573.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">246</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">567</span> Effect of Impact Angle on Erosive Abrasive Wear of Ductile and Brittle Materials</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ergin%20Kosa">Ergin Kosa</a>, <a href="https://publications.waset.org/abstracts/search?q=Ali%20G%C3%B6ksenli"> Ali Göksenli</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Erosion and abrasion are wear mechanisms reducing the lifetime of machine elements like valves, pump and pipe systems. Both wear mechanisms are acting at the same time, causing a “Synergy” effect, which leads to a rapid damage of the surface. Different parameters are effective on erosive abrasive wear rate. In this study effect of particle impact angle on wear rate and wear mechanism of ductile and brittle materials was investigated. A new slurry pot was designed for experimental investigation. As abrasive particle, silica sand was used. Particle size was ranking between 200-500 µm. All tests were carried out in a sand-water mixture of 20% concentration for four hours. Impact velocities of the particles were 4,76 m/s. As ductile material steel St 37 with Brinell Hardness Number (BHN) of 245 and quenched St 37 with 510 BHN was used as brittle material. After wear tests, morphology of the eroded surfaces were investigated for better understanding of the wear mechanisms acting at different impact angles by using optical microscopy and Scanning Electron Microscope. The results indicated that wear rate of ductile material was higher than brittle material. Maximum wear was observed by ductile material at a particle impact angle of 300. On the contrary wear rate increased by brittle materials by an increase in impact angle and reached maximum value at 450. High amount of craters were detected after observation on ductile material surface Also plastic deformation zones were detected, which are typical failure modes for ductile materials. Craters formed by particles were deeper according to brittle material worn surface. Amount of craters decreased on brittle material surface. Microcracks around craters were detected which are typical failure modes of brittle materials. Deformation wear was the dominant wear mechanism on brittle material. At the end it is concluded that wear rate could not be directly related to impact angle of the hard particle due to the different responses of ductile and brittle materials. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=erosive%20wear" title="erosive wear">erosive wear</a>, <a href="https://publications.waset.org/abstracts/search?q=particle%20impact%20angle" title=" particle impact angle"> particle impact angle</a>, <a href="https://publications.waset.org/abstracts/search?q=silica%20sand" title=" silica sand"> silica sand</a>, <a href="https://publications.waset.org/abstracts/search?q=wear%20rate" title=" wear rate"> wear rate</a>, <a href="https://publications.waset.org/abstracts/search?q=ductile-brittle%20material" title=" ductile-brittle material"> ductile-brittle material</a> </p> <a href="https://publications.waset.org/abstracts/35312/effect-of-impact-angle-on-erosive-abrasive-wear-of-ductile-and-brittle-materials" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/35312.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">401</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">566</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. The coating is deposited on by physical vapor deposition (PVD) method. The working conditions of the blade were simulated and surface temperature and pressure values as well as flow velocity and flow direction were obtained. 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. Results show that the life of the TiN-coated blade is approximately 1.76 times longer than the life of the uncoated one. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=physical%20vapour%20deposition" title="physical vapour deposition">physical vapour deposition</a>, <a href="https://publications.waset.org/abstracts/search?q=steam%20turbine%20blade" title=" steam turbine blade"> steam turbine blade</a>, <a href="https://publications.waset.org/abstracts/search?q=titanium-based%20coating" title=" titanium-based coating"> titanium-based coating</a>, <a href="https://publications.waset.org/abstracts/search?q=wear%20prediction" title=" wear prediction"> wear prediction</a> </p> <a href="https://publications.waset.org/abstracts/8420/computational-study-and-wear-prediction-of-steam-turbine-blade-with-titanium-nitride-coating-deposited-by-physical-vapor-deposition-method" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/8420.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">373</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">565</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.

Inadequate housing sites associated with an inefficient urban drainage network and lack of vegetation cover potentiate the erosive processes that, over time, are gaining alarming proportions, as is the case of the erosion in Planaltina in Federal district, a Brazilian state in the central west. Thus, the aim of this work was to compare the use of Vetiver grass and Alfalfa as vegetation cover to slope protection. For that, a study was carried out in the scientific literature about the improvement of the soil properties provided by them and verification of the safety factor through the simulation of slopes with different heights and inclination using SLOPE / W software. The Vetiver grass presented little more satisfactory results than the Alfalfa, but these obtained results slightly closer to that of the vetiver grass in less time of planting. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=erosive%20processes" title="erosive processes">erosive processes</a>, <a href="https://publications.waset.org/abstracts/search?q=planting" title=" planting"> planting</a>, <a href="https://publications.waset.org/abstracts/search?q=slope%20protection" title=" slope protection"> slope protection</a>, <a href="https://publications.waset.org/abstracts/search?q=vegetation%20cover" title=" vegetation cover"> vegetation cover</a> </p> <a href="https://publications.waset.org/abstracts/99460/use-of-vegetative-coverage-for-slope-stability-in-the-brazilian-midwest-case-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/99460.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">180</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">562</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. It is found that surface modification has significant effect on sliding wear performance of Perspex. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Perspex" title="Perspex">Perspex</a>, <a href="https://publications.waset.org/abstracts/search?q=wear" title=" wear"> wear</a>, <a href="https://publications.waset.org/abstracts/search?q=friction" title=" friction"> friction</a>, <a href="https://publications.waset.org/abstracts/search?q=SEM" title=" SEM"> SEM</a> </p> <a href="https://publications.waset.org/abstracts/73593/wet-sliding-wear-and-frictional-behavior-of-commercially-available-perspex" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/73593.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">272</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">560</span> Wear Particle Analysis from used Gear Lubricants for 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 particular work describes an experimental investigation on gear wear 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.

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">559</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">557</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">555</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">554</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">353</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">553</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.

As a result of the landslide movement, freshets and mudflows originated, and unfortunately, there were victims: zoo animals and birds were drawn in the flood and 12 people died due to the flooded motor road. The goal of the study is to give the analysis of the results of the field and scientific research held in 2015-2017 and to generalize them to the water catch basins of the erosive-mudflow rivers of other mountain landscapes of Georgia. By considering the field and scientific works, the main geographic, geological, climatic, hydrological and hydraulic properties of the erosive-mudflow tributaries of the water catch basin of the river Vere were evaluated and the probabilities of mudflow formation by considering relevant risk-factors were identified. The typology of the water catch basins of erosive-mudflow rivers of Georgia was identified on the example of the river Vere based on the field and scientific study, and their genesis, frequency of mudflow formation and volume of the drift material was identified. By using the empirical and theoretical dependencies, the amount of solid admixtures in the mudflow formed in the gorge of the river Jokhona, the right tributary of the river Vere was identified by considering the shape of the stones. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=water%20catchment%20basin" title="water catchment basin">water catchment basin</a>, <a href="https://publications.waset.org/abstracts/search?q=erosion" title=" erosion"> erosion</a>, <a href="https://publications.waset.org/abstracts/search?q=mudflow" title=" mudflow"> mudflow</a>, <a href="https://publications.waset.org/abstracts/search?q=typology" title=" typology"> typology</a> </p> <a href="https://publications.waset.org/abstracts/80110/analysis-and-evaluation-of-the-water-catch-basins-of-the-erosive-mudflow-rivers-of-georgia-on-the-example-of-the-river-vere" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/80110.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">276</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">549</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">548</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">547</span> Field Studies of 2017 in the Water Catch Basin in the River Vere to Safeguard the Population of Tbilisi against the Erosive-Mudflow Processes and Its Evaluation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Natia%20Gavardashvili">Natia Gavardashvili</a> </p> <p class="card-text"><strong>Abstract:</strong></p> From April through June of 2017, the field-scientific studies to ensure the safety of the population of Tbilisi were accomplished in the water catch basin of the river Vere, in the water catch basin of the river Jakhana dry gully. 5 sensitive sites were identified, and areas, 20x20 m each, were marked around them, with their locations fixed with GPS coordinates. The gained areas were plotted on a digital map, and the state of the surface was explored by considering the evaluation of erosive processes. Aiming at evaluating the soils and grounds of the sensitive areas, the ground samples were taken, and average diameter was identified, with its value changing to D0 = 4,67-15,48 mm, and integral curves of the grain size were drafted. By using the obtained data, the transporting capability of mudflow can be identified at the next stage to use to calculate mudflow peak discharges of different provisions in developing the new designs of mudflow-protection structures with the goal of ensuring the safety of Tbilisi population.

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">545</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 href="https://publications.waset.org/abstracts/search?q=Cu-based%20friction%20materials" title="Cu-based friction materials">Cu-based friction materials</a>, <a href="https://publications.waset.org/abstracts/search?q=Fe%20reinforcement" title=" Fe reinforcement"> Fe reinforcement</a>, <a href="https://publications.waset.org/abstracts/search?q=wear%20map" title=" wear map"> wear map</a>, <a href="https://publications.waset.org/abstracts/search?q=wear%20mechanism" title=" wear mechanism"> wear mechanism</a> </p> <a href="https://publications.waset.org/abstracts/64328/wear-map-for-cu-based-friction-materials-with-different-contents-of-fe-reinforcement" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/64328.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">279</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">542</span> Dynamic Simulation for Surface Wear Prognosis of the Main Bearings in the Internal Combustion Engine</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yanyan%20Zhang">Yanyan Zhang</a>, <a href="https://publications.waset.org/abstracts/search?q=Ziyu%20Diao"> Ziyu Diao</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 wear character of the main bearing is one of the critical indicators for the overhaul of an internal combustion engine, and the aim of this paper is to reveal the dynamic wear mechanism of the main bearings.

These blades are generally produced from low carbon or low alloy steel. During the field work i.e. preparing land for the cultivation these blades are subjected to severe wear conditions. Comparative wear tests on a regular rotavator blade and two kinds of hardfacing with electrodes were conducted in the field. These two different hardfacing electrodes, which are designated HARD ALLOY-400 and HARD ALLOY-650, were used for hardfacing.

An electric resistance furnace was used to produce alloys. Pure Mg together with Al, Al-Ti and Al-Mn were melted at 750 <sup>0</sup>C in a stainless steel crucible under controlled Ar gas atmosphere and then poured into a metal mould preheated at 250 <sup>0</sup>C. Microstructure characterizations were performed by light optical (LOM) and scanning electron microscope (SEM) after the wear test. Wear rates and friction coefficients were measured with a pin-on-disk type UTS-10 Tribometer test device under a load of 20N. The results showed that Ti addition altered the morphology and the amount of b-Mg<sub>17</sub>Al<sub>12</sub> phase in the microstructure of AM60 alloy. b-Mg<sub>17</sub>Al<sub>12</sub> phases on the grain boundaries were refined with increasing amount of Ti. An improvement in wear resistance of AM60 alloy was observed due to the alteration in the microstructure by Ti addition. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=magnesium%20alloy" title="magnesium alloy">magnesium alloy</a>, <a href="https://publications.waset.org/abstracts/search?q=titanium" title=" titanium"> titanium</a>, <a href="https://publications.waset.org/abstracts/search?q=SEM" title=" SEM"> SEM</a>, <a href="https://publications.waset.org/abstracts/search?q=wear" title=" wear"> wear</a> </p> <a href="https://publications.waset.org/abstracts/52098/influence-of-titanium-addition-on-wear-properties-of-am60-magnesium-alloy" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/52098.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">334</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">539</span> Wear and Fraction Behavior of Porcelain Coated with Polyurethane/SiO2 Coating Layer</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ching%20Yern%20Chee">Ching Yern Chee</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Various loading of nano silica is added into polyurethane (PU) and then coated on porcelain substrate. The wear and friction properties of the porcelain substrates coated with polyurethane/nano silica nano composite coatings were investigated using the reciprocating wear testing machine. The friction and wear test of polyurethane/nano silica coated porcelain substrate was studied at different sliding speed and applied load. It was found that the optimum composition of nano silica is 3 wt% which gives the lowest friction coefficient and wear rate in all applied load ranges and sliding speeds. For 3 wt% nano silica filled PU coated porcelain substrate, the increment of sliding speed caused higher wear rates but lower frictions coefficient. Besides, the friction coefficient of nano silica filled PU coated porcelain substrate decreased but the wear rate increased with the applied load. <p class="card-text"><strong>Keywords:</strong> <a
