The results of the isothermal oxidation showed that the formation of Si-aluminide coating can remarkably improve the high temperature oxidation of bare gamma-TiAl alloy. The identification of oxide scale microstructure showed that the formation of protective Al<sub>2</sub>O<sub>3</sub>+SiO<sub>2</sub> mixed oxide scale along with a continuous, compact and uniform layer of Ti<sub>5</sub>Si<sub>3</sub> beneath the surface oxide scale can act as an oxygen diffusion barrier during the high temperature oxidation.

In this method, the substrate is dipped into a molten aluminum bath, hold in the bath for several minutes, and cooled down to the room temperature in air. A subsequent annealing after the HDA process is generally performed. The main advantage of HDA is its very low investment cost in comparison with other aluminizing methods such as chemical vapor deposition (CVD), pack aluminizing and metalizing. In the HDA process, Al or Al-Si molten baths are mostly used. However, in this study, three different Al alloys such as Al4043 (Al-Mg), Al5356 (Al-Si) and Al7020 (Al-Zn) were used as the molten bath in order to see their effects on morphological and mechanical properties of the resulting aluminide layers. AISI 4140 low alloyed steel was used as the substrate. Parameters of the HDA process were bath composition, bath temperature, and dipping time. These parameters were considered within a Taguchi L9 orthogonal array. After the HDA process and subsequent diffusion annealing, coating thickness measurement, microstructural analysis and hardness measurement of the aluminide layers were conducted. The optimum process parameters were evaluated according to coating morphology, such as cracks, Kirkendall porosity and hardness of the coatings. According to the results, smooth and clean aluminide layer with less Kirkendall porosity and cracks were observed on the sample, which was aluminized in the molten Al7020 bath at 700 C for 10 minutes and subsequently diffusion annealed at 750 C. Hardness of the aluminide layer was in between 1100-1300 HV and the coating thickness was approximately 400 µm. The results were promising such that a hard and thick aluminide layer with less Kirkendall porosity and cracks could be formed. It is, therefore, concluded that Al7020 bath may be used in the HDA process of AISI 4140 steel substrate. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=hot-dip%20aluminizing" title="hot-dip aluminizing">hot-dip aluminizing</a>, <a href="https://publications.waset.org/abstracts/search?q=microstructure" title=" microstructure"> microstructure</a>, <a href="https://publications.waset.org/abstracts/search?q=hardness%20measurement" title=" hardness measurement"> hardness measurement</a>, <a href="https://publications.waset.org/abstracts/search?q=diffusion%20annealing" title=" diffusion annealing"> diffusion annealing</a> </p> <a href="https://publications.waset.org/abstracts/174006/the-effect-of-bath-composition-for-hot-dip-aluminizing-of-aisi-4140-steel" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/174006.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">76</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">434</span> The Effect of Substrate Surface Roughness for Hot Dip Aluminizing of IN718 Alloy</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Aptullah%20Karakas">Aptullah Karakas</a>, <a href="https://publications.waset.org/abstracts/search?q=Murat%20Baydogan"> Murat Baydogan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The hot dip aluminizing (HDA) process involves immersing a metallic substrate into a molten aluminum bath for several minutes, and removed from the bath and cooled down to room temperature. After the HDA process, various aluminide layers are formed as a result of interdiffusion between the substrate and the molten aluminum and between the aluminide layers. In order to form a uniform aluminide layer, the specimen must be covered and wet well by the molten aluminum. Surface roughness plays an important role in wettability, and thus, surface preparation is an important stage in determining the final surface roughness. In this study, different roughness values were achieved by grinding the surface with emery papers as 180, 320 and 600 grids. After the surface preparation, the HDA process was performed in a molten Al-Si bath at 700 ᴼC for 10 minutes. After the HDA process, a microstructural examination of the coating was carried out to evaluate the uniformity of the coating and adhesion between the substrate and the coating. According to the results, the best adhesion at the interface was observed on the specimen, which was prepared by 320 grid emery paper having a mean surface roughness (Ra) of 0.097 µm. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=hot-dip%20aluminizing" title="hot-dip aluminizing">hot-dip aluminizing</a>, <a href="https://publications.waset.org/abstracts/search?q=microstructure" title=" microstructure"> microstructure</a>, <a href="https://publications.waset.org/abstracts/search?q=surface%20roughness" title=" surface roughness"> surface roughness</a>, <a href="https://publications.waset.org/abstracts/search?q=coating" title=" coating"> coating</a> </p> <a href="https://publications.waset.org/abstracts/183339/the-effect-of-substrate-surface-roughness-for-hot-dip-aluminizing-of-in718-alloy" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/183339.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">70</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">433</span> Thermodynamics of Chlorination of Acid-Soluble Titanium Slag in Molten Salt for Preparation of TiCl4</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Li%20Liang">Li Liang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Chinese titanium iron ore reserves with high calcium and magnesium accounted for more than 90% of the total reserves, and acid-soluble titanium slag which is produced by titanium iron ore always used to produce titanium dioxide through sulphate process.

In order to produce titanium powders, it is necessary to melt titanium, and generally it is conducted by an induction heating method using Al₂O₃ ceramic crucible. However, since titanium reacts chemically with Al₂O₃, it is difficult to melt titanium by the induction heating method using Al₂O₃ crucible. To avoid this problem, we studied the chemical stability of the various crucibles such as Al₂O₃, MgO, ZrO₂, and Y₂O₃ crucibles to molten titanium. After titanium lumps (Grade 2, O(oxygen)<0.25wt%) were placed in each crucible, they were heated to 1800℃ with a heating rate of 5 ℃/min, held at 1800℃ for 30 min, and finally cooled to room temperature with a cooling rate of 5 ℃/min. All heat treatments were carried out in high purity Ar atmosphere. To evaluate the chemical stability, thermodynamic data such as Ellingham diagram were utilized, and also Vickers hardness test, microstructure analysis, and EPMA quantitative analysis were performed. As a result, Al₂O₃, MgO and ZrO₂ crucibles chemically reacted with molten titanium, but Y₂O₃ crucible rarely reacted with it. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=titanium" title="titanium">titanium</a>, <a href="https://publications.waset.org/abstracts/search?q=induction%20melting" title=" induction melting"> induction melting</a>, <a href="https://publications.waset.org/abstracts/search?q=crucible" title=" crucible"> crucible</a>, <a href="https://publications.waset.org/abstracts/search?q=chemical%20stability" title=" chemical stability"> chemical stability</a> </p> <a href="https://publications.waset.org/abstracts/77805/chemical-stability-of-ceramic-crucibles-to-molten-titanium" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/77805.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">301</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">430</span> Mechanical and Microstructural Properties of Rotary-Swaged Wire of Commercial-Purity Titanium</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Michal%20Duchek">Michal Duchek</a>, <a href="https://publications.waset.org/abstracts/search?q=Jan%20Pal%C3%A1n"> Jan Palán</a>, <a href="https://publications.waset.org/abstracts/search?q=Tomas%20Kubina"> Tomas Kubina</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Bars made of titanium grade 2 and grade 4 were subjected to rotary forging with up to 2.2 true strain reduction in the cross-section from 10 to 3.81 mm.

These studies were carried out using different media in which the powders were incubated for a specific time. These were: water, SBF, and Ringer's solution. The release of titanium ions from modified products is weaker compared to unmodified titanium oxide nanoparticles. The reduced release of titanium ions may allow the use of such modified materials as substances in drug delivery systems. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=titanium%20dioxide" title="titanium dioxide">titanium dioxide</a>, <a href="https://publications.waset.org/abstracts/search?q=nanoparticles" title=" nanoparticles"> nanoparticles</a>, <a href="https://publications.waset.org/abstracts/search?q=drug%20carrier" title=" drug carrier"> drug carrier</a>, <a href="https://publications.waset.org/abstracts/search?q=glutathione" title=" glutathione"> glutathione</a> </p> <a href="https://publications.waset.org/abstracts/142599/titanium-dioxide-modified-with-glutathione-as-potential-drug-carrier-with-reduced-toxic-properties" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/142599.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">160</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">427</span> Biological Evaluation of Some Modern Titanium Alloys for Dental Implants</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Roxana%20Maria%20Angelescu">Roxana Maria Angelescu</a>, <a href="https://publications.waset.org/abstracts/search?q=Raluca%20Ion"> Raluca Ion</a>, <a href="https://publications.waset.org/abstracts/search?q=Ani%C5%9Foara%20C%C3%AEmpean"> Anişoara Cîmpean</a>, <a href="https://publications.waset.org/abstracts/search?q=Doina%20R%C4%83ducanu"> Doina Răducanu</a>, <a href="https://publications.waset.org/abstracts/search?q=Mariana%20Lucia%20Angelescu"> Mariana Lucia Angelescu </a> </p> <p class="card-text"><strong>Abstract:</strong></p> In an attempt to find titanium alloys that fulfill the requirements for mechanical and biological compatibility, laboratory and material related tests were performed during the years, as well as preclinical and clinical trials. The multidisciplinary scientific research facilitates the global evaluation of biocompatibility and osseointegration regarding the dental implant alloys. The aim of this study was to determine the in vitro biocompatibility of three modern titanium alloys: Ti-31.7Nb-6.21Zr-1.4Fe-0.16O (wt%), Ti-36.5Nb-4.5Zr-3Ta-0.16O (wt%) and Ti-20Nb-5Ta (wt%), in order to establish whether the use of these titanium alloys can have any toxic or injurious effects on biological systems. The commonly used Ti-6Al-4V alloy was investigated as a reference material. The behavior of MC3T3-E1 pre-osteoblasts on all these four metallic surfaces was evaluated. The tests of immunofluorescence, cytotoxicity and cellular proliferation lead to the conclusion that the newly-developed titanium alloys elicit a good cellular response in terms of cellular survival, adhesion, morphology and proliferative potential as well. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=biocompatibility%20tests" title="biocompatibility tests">biocompatibility tests</a>, <a href="https://publications.waset.org/abstracts/search?q=dental%20implants" title=" dental implants"> dental implants</a>, <a href="https://publications.waset.org/abstracts/search?q=titanium%20alloys" title=" titanium alloys"> titanium alloys</a>, <a href="https://publications.waset.org/abstracts/search?q=biomedical%20engineering" title=" biomedical engineering"> biomedical engineering</a> </p> <a href="https://publications.waset.org/abstracts/27562/biological-evaluation-of-some-modern-titanium-alloys-for-dental-implants" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/27562.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">502</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">426</span> Surface Modification of Titanium Alloy with Laser Treatment</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nassier%20A.%20Nassir">Nassier A.

The influence of the laser surface treatment on the bonding strength between the titanium and poly-ether-ketone-ketone (PEKK) surfaces was also evaluated and compared to those offered by titanium foils without surface treatment to optimize the laser parameters. Material characterization using an optical microscope was carried out to study the microstructure and to measure the mean roughness value of the titanium surface. The results showed that the surface roughness shows a significant dependency on the laser power parameters in which surface roughness increases with the laser power increment. Moreover, the results of the tensile tests have shown that there is no significant dropping in tensile strength for the treated samples comparing to the virgin ones. In order to optimize the laser parameter as well as the corresponding surface roughness, single-lap shear tests were conducted on pairs of the laser treated titanium stripes. The results showed that the bonding shear strength between titanium alloy and PEKK film increased with the surface roughness increment to a specific limit. After this point, it is interesting to note that there was no significant effect for the laser parameter on the bonding strength. This evidence suggests that it is not necessary to use very high power of laser to treat titanium surface to achieve a good bonding strength between titanium alloy and the PEKK film. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bonding%20strength" title="bonding strength">bonding strength</a>, <a href="https://publications.waset.org/abstracts/search?q=laser%20surface%20treatment" title=" laser surface treatment"> laser surface treatment</a>, <a href="https://publications.waset.org/abstracts/search?q=PEKK" title=" PEKK"> PEKK</a>, <a href="https://publications.waset.org/abstracts/search?q=poly-ether-ketone-ketone" title="poly-ether-ketone-ketone">poly-ether-ketone-ketone</a>, <a href="https://publications.waset.org/abstracts/search?q=titanium%20alloy" title=" titanium alloy"> titanium alloy</a> </p> <a href="https://publications.waset.org/abstracts/92507/surface-modification-of-titanium-alloy-with-laser-treatment" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/92507.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">338</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">425</span> Wear Behavior of Intermetallic (Ni3Al) Coating at High Temperature </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=K.%20Mehmood">K.

After thermal spraying, the nickel aluminide intermetallic coatings were isothermal heat treated at various temperatures. In this regard, temperatures from 500 °C to 800 °C with 100 °C increments were selected. The coatings were soaked for 10, 30, 60 and 100 hours at the mentioned temperatures. These coatings were then tested by a pin on disk method. It was observed that the coatings exposed at comparatively higher temperature experienced lower wear rate. The decrease in wear rate is due to the formation of NiO phase. Further, the as sprayed and heat treated coatings were characterized by other tools such as Microhardness testing, optical and scanning electron microscopy (SEM) and X-Ray diffraction analysis. After isothermal heat treatment, NiO was observed the main phase by X-Ray diffraction technique.

In this work, an approach for fabricating porous spheres of nanoparticles was presented, in which the nanoparticles were welded together to form micro spheres by simply irradiating the nanoparticles in liquid medium by a picosecond laser. As an example, anatase titanium dioxide was chosen as a typical material on account of its metastability. The structure and morphologies of the products were characterised by X-ray diffraction (XRD), scanning electron microscope (SEM), Raman, and high-resolution transmission electron microscopy (HRTEM), respectively. The results showed that, anatase titanium dioxide micro spheres (2-10 μm) with macroporous (10-100 nm) were prepared from nano-anatase titanium dioxide nanoparticles (10-100 nm). The formation process of polycrystalline anatase titanium dioxide microspheres was investigated with different liquid mediums and the input laser fluences. Thus, this facile laser irradiation approach might provide a way for the fabrication of porous microspheres without phase-transition. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=titanium%20dioxide" title="titanium dioxide">titanium dioxide</a>, <a href="https://publications.waset.org/abstracts/search?q=porous%20microspheres" title=" porous microspheres"> porous microspheres</a>, <a href="https://publications.waset.org/abstracts/search?q=picosecond%20laser" title=" picosecond laser"> picosecond laser</a>, <a href="https://publications.waset.org/abstracts/search?q=nano-welding" title=" nano-welding"> nano-welding</a> </p> <a href="https://publications.waset.org/abstracts/61694/one-step-synthesis-of-titanium-dioxide-porous-microspheres-by-picosecond-pulsed-laser-welding" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/61694.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">305</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">422</span> A Brief Review of Titanium Powders Used in Laser Powder-Bed Fusion Additive Manufacturing</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ali%20Alhajeri">Ali Alhajeri</a>, <a href="https://publications.waset.org/abstracts/search?q=Tarig%20Makki"> Tarig Makki</a>, <a href="https://publications.waset.org/abstracts/search?q=Mosa%20Almutahhar"> Mosa Almutahhar</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammed%20Ahmed"> Mohammed Ahmed</a>, <a href="https://publications.waset.org/abstracts/search?q=Usman%20Ali"> Usman Ali</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Metal powder is the raw material used for laser powder-bed fusion (LPBF) additive manufacturing (AM).

In this investigation, the application of USM process for machining of titanium (ASTM Grade-I) has been explored. Experiments have been conducted to assess the effect of different parameters of USM process on machining rate and tool wear rate as response characteristics. The process parameters that were included in this study are: abrasive grit size, tool material and power rating of the ultrasonic machine.

Besides other important material features, the corrosion parameters and corrosion products are responsible for limiting the biological and chemical bio compatibility of metallic materials that produce undesirable reactions in implant-adjacent and/or more distant tissues. Electrochemical corrosion behaviors of novel beta titanium alloys, Ti-4.7Mo-4.5Fe, Ti-3Mo-0.5Fe, and Ti-2Mo-0.5Fe were characterized in naturally aerated Ringer’s solution at room temperature compared with common used biomedical titanium alloy, Ti-6Al-4V. The corrosion resistance of titanium alloys were investigated through open circuit potential (OCP), potentiodynamic polarization measurements and optical microscope (OM). A high corrosion resistance was obtained for all alloys due to the stable passive film formed on their surfaces. The new present alloys are promising metallic biomaterials for the future, owing to their very low elastic modulus and good corrosion resistance capabilities. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=titanium%20alloys" title="titanium alloys">titanium alloys</a>, <a href="https://publications.waset.org/abstracts/search?q=corrosion%20resistance" title=" corrosion resistance"> corrosion resistance</a>, <a href="https://publications.waset.org/abstracts/search?q=Ringer%E2%80%99s%20solution" title=" Ringer’s solution"> Ringer’s solution</a>, <a href="https://publications.waset.org/abstracts/search?q=electrochemical%20corrosion" title=" electrochemical corrosion"> electrochemical corrosion</a> </p> <a href="https://publications.waset.org/abstracts/19503/electrochemical-corrosion-behavior-of-new-developed-titanium-alloys-in-ringers-solution" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/19503.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">658</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">418</span> Biocompatible Beta Titanium Alloy Ti36Nb6Ta as a Suitable Material for Bone Regeneration</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Vera%20Lukasova">Vera Lukasova</a>, <a href="https://publications.waset.org/abstracts/search?q=Eva%20Filova"> Eva Filova</a>, <a href="https://publications.waset.org/abstracts/search?q=Jana%20Dankova"> Jana Dankova</a>, <a href="https://publications.waset.org/abstracts/search?q=Vera%20Sovkova"> Vera Sovkova</a>, <a href="https://publications.waset.org/abstracts/search?q=Matej%20Daniel"> Matej Daniel</a>, <a href="https://publications.waset.org/abstracts/search?q=Michala%20Rampichova"> Michala Rampichova</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Proper bone implants should promote fast adhesion of cells, stimulate cell differentiation and support the formation of bone tissue. Nowadays titanium is used as a biocompatible material capable of bone tissue integration. This study was focused on comparison of bioactive properties of two titanium alloys - beta titanium alloy Ti36Nb6Ta and standard medical titanium alloy Ti6A14V. The advantage of beta titanium alloy Ti36Nb6Ta is mainly that this material does not contain adverse elements like vanadium or aluminium. Titanium alloys were sterilized in ethanol, placed into 48 well plates and seeded with porcine mesenchymal stem cells. Cells were cultivated for 14 days in standard growth cultivation media with osteogenic supplements. Cell metabolic activity was quantified using MTS assay (Promega). Cell adhesion on day 1 and cell proliferation on further days were verified immunohistochemically using beta-actin monoclonal antibody and secondary antibody conjugated with AlexaFluor®488. Differentiation of cells was evaluated using alkaline phosphatase assay. Additionally, gene expression of collagen I was measured by qRT-PCR. Porcine mesenchymal stem cells adhered and spread well on beta titanium alloy Ti36Nb6Ta on day 1. During the 14 days’ time period the cells were spread confluently on the surface of the beta titanium alloy Ti36Nb6Ta. The metabolic activity of cells increased during the whole cultivation period. In comparison to standard medical titanium alloy Ti6A14V, we did not observe any differences. Moreover, the expression of collagen I gene revealed no statistical differences between both titanium alloys. Therefore, a beta titanium alloy Ti36Nb6Ta promotes cell adhesion, metabolic activity, proliferation and collagen I expression equally to standard medical titanium alloy Ti6A14V. Thus, beta titanium is a suitable material that provides sufficient biocompatible properties.

The present work was mainly to study the effects of treatment time of PEO process on properties of the titanium coating. A potentiodynamic polarization corrosion test was employed to investigate the corrosion resistance of the coating. The friction coefficient and wear resistance of the coating were studied by using pin-on-disc test. The thermal transfer behaviours of uncoated and PEO-coated aluminized steels were also studied. It could be seen that treatment time of PEO process significantly influenced the properties of the titanium oxide coating. Samples with a longer treatment time had a better performance for corrosion and wear protection.

Property evaluation of scaffolds confirmed a high level of compatibility between their mechanical properties and those of human cortical bone. The optimum sintering temperature was found to be 1250°C producing scaffolds with more than 90% interconnected pores in the size range of 200-250 µm, yield stress of 220 MPa and Young’s modulus of 7.80 GPa, all of which are suitable for bone tissue engineering. Increasing the sintering temperature to 1300°C increased the Young’s modulus to 22.0 GPa while reducing the temperature to 1150°C reduced the yield stress to 120 MPa due to incomplete sintering. The residual potassium chloride was determined vs. sintering temperature.

Zemko</a> </p> <p class="card-text"><strong>Abstract:</strong></p> COMTES FHT has been active in a field of research and development of high-strength wires for quite some time. The main material was pure titanium. The primary goal of this effort is to develop a continuous production process for ultrafine and nanostructured materials with the aid of severe plastic deformation (SPD). This article outlines mechanical and microstructural properties of the materials and the options available for testing the components made of these materials. Ti Grade 2 and Grade 4 wires are the key products of interest. Ti Grade 2 with ultrafine to nano-sized grain shows ultimate strength of up to 1050 MPa. Ti Grade 4 reaches ultimate strengths of up to 1250 MPa. These values are twice or three times as higher as those found in the unprocessed material. For those fields of medicine where implantable metallic materials are used, bulk ultrafine to nanostructured titanium is available. It is manufactured by SPD techniques. These processes leave the chemical properties of the initial material unchanged but markedly improve its final mechanical properties, in particular, the strength. Ultrafine to nanostructured titanium retains all the significant and, from the biological viewpoint, desirable properties that are important for its use in medicine, i.e. those properties which made pure titanium the preferred material also for dental implants. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=CONFORM" title="CONFORM">CONFORM</a>, <a href="https://publications.waset.org/abstracts/search?q=ECAP" title=" ECAP"> ECAP</a>, <a href="https://publications.waset.org/abstracts/search?q=rotary%20swaging" title=" rotary swaging"> rotary swaging</a>, <a href="https://publications.waset.org/abstracts/search?q=titanium" title=" titanium"> titanium</a> </p> <a href="https://publications.waset.org/abstracts/73209/the-high-strength-biocompatible-wires-of-commercially-pure-titanium" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/73209.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">243</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">413</span> Preparation of Catalyst-Doped TiO2 Nanotubes by Single Step Anodization and Potential Shock </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hyeonseok%20Yoo">Hyeonseok Yoo</a>, <a href="https://publications.waset.org/abstracts/search?q=Kiseok%20Oh"> Kiseok Oh</a>, <a href="https://publications.waset.org/abstracts/search?q=Jinsub%20Choi"> Jinsub Choi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Titanium oxide nanotubes have attracted great attention because of its photocatalytic activity and large surface area. For enhancing electrochemical properties, catalysts should be doped into the structure because titanium oxide nanotubes themselves have low electroconductivity and catalytic activity. It has been reported that Ru and Ir doped titanium oxide electrodes exhibit high efficiency and low overpotential in the oxygen evolution reaction (OER) for water splitting. In general, titanium oxide nanotubes with high aspect ratio cannot be easily doped by conventional complex methods. Herein, two types of facile routes, namely single step anodization and potential shock, for Ru doping into high aspect ratio titanium oxide nanotubes are introduced in detail. When single step anodization was carried out, stability of electrodes were increased. However, onset potential was shifted to anodic direction. On the other hand, when high potential shock voltage was applied, a large amount of ruthenium/ruthenium oxides were doped into titanium oxide nanotubes and thick barrier oxide layers were formed simultaneously. Regardless of doping routes, ruthenium/ ruthenium oxides were homogeneously doped into titanium oxide nanotubes. In spite of doping routes, doping in aqueous solution generally led to incorporate high amount of Ru in titanium oxide nanotubes, compared to that in non-aqueous solution. The amounts of doped catalyst were analyzed by X-ray photoelectron spectroscopy (XPS). The optimum condition for water splitting was investigated in terms of the amount of doped Ru and thickness of barrier oxide layer. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=doping" title="doping">doping</a>, <a href="https://publications.waset.org/abstracts/search?q=potential%20shock" title=" potential shock"> potential shock</a>, <a href="https://publications.waset.org/abstracts/search?q=single%20step%20anodization" title=" single step anodization"> single step anodization</a>, <a href="https://publications.waset.org/abstracts/search?q=titanium%20oxide%20nanotubes" title=" titanium oxide nanotubes"> titanium oxide nanotubes</a> </p> <a href="https://publications.waset.org/abstracts/36644/preparation-of-catalyst-doped-tio2-nanotubes-by-single-step-anodization-and-potential-shock" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/36644.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">458</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">412</span> Effect of Structure on Properties of Incrementally Formed Titanium Alloy Sheets</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Lucie%20Novakova">Lucie Novakova</a>, <a href="https://publications.waset.org/abstracts/search?q=Petr%20Homola"> Petr Homola</a>, <a href="https://publications.waset.org/abstracts/search?q=Vaclav%20Kafka"> Vaclav Kafka</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Asymmetric incremental sheet forming (AISF) could significantly reduce costs incurred by the fabrication of complex industrial components with a minimal environmental impact. The AISF experiments were carried out on commercially pure titanium (Ti-Gr2), Timetal (15-3-3-3) alloy, and Ti-6Al-4V (Ti-Gr5) alloy. A special testing geometry was used to characterize the titanium alloys properties from the point of view of the forming zone and titanium structure effect. The structure and properties of the materials were assessed by means of metallographic analyses and microhardness measurements.The highest differences in the parameters assessed as a function of the sampling zone were observed in the case of alpha-phase Ti-Gr2at the expense of the most substantial sheet thinning occurrence. A springback causes a smaller stored deformation in Timetal (β alloy) resulting in less pronounced microstructure refinement and microhardness increase. Ti-6Al-4V alloy exhibited early failure due to its poor formability at ambient temperature. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=incremental%20forming" title="incremental forming">incremental forming</a>, <a href="https://publications.waset.org/abstracts/search?q=metallography" title=" metallography"> metallography</a>, <a href="https://publications.waset.org/abstracts/search?q=hardness" title=" hardness"> hardness</a>, <a href="https://publications.waset.org/abstracts/search?q=titanium%20alloys" title=" titanium alloys"> titanium alloys</a> </p> <a href="https://publications.waset.org/abstracts/5510/effect-of-structure-on-properties-of-incrementally-formed-titanium-alloy-sheets" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/5510.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">450</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">411</span> Diffusion Treatment of Niobium and Molybdenum on Pur Titanium and Titanium Alloy Ti-64al and Their Properties </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kaouka%20Alaeddine">Kaouka Alaeddine</a>, <a href="https://publications.waset.org/abstracts/search?q=K.%20Benarous"> K.

Two agents metal alloy have been used in this treatment, niobium (Nb) and molybdenum (Mo), spread on elemental titanium and Ti-64Al alloy. Nb and Mo are used as powder form to increase the contact surface and to improve the distribution. Both Mo and Nb are distributed on samples of Ti and Ti-64Al at 1100 °C and 1200 °C for 3 h. They were performed to effect different experiments objectives. This work was achieved to improve some properties and microstructure of Ti and Ti-64Al surface, using optical microscopy and SEM and study some mechanical properties. The effects of temperature and the powder contents on the microstructure of Ti and Ti-64Al alloy, different phases and hardness value of Ti and Ti-64Al alloy were determined. Experimental results indicate that increasing the powder contents and/or the temperature, the α + β phases change to the equiaxed β lamellar structure. In particular, experiments in 1200 °C were created by diffusion α + β phases both equiaxed β phase laminar and α + β phase, thus meeting the objectives were established in the work.

One major issue of concern for the sheet forming of titanium alloys is their high sensitivity to surface inhomogeneity. Various machining processes are utilised in preparing sheet hole edges for edge flanging applications. However, the response of edge forming tendencies of titanium to different edge surface finishes is not well investigated. The hole expansion test is used in this project to elucidate the impact of abrasive water jet (AWJ) and electro-discharge machining (EDM) cutting techniques on the edge formability of CP-Ti (Grade 2) and Ti-3Al-2.5V alloys at room temperature. The results show that the quality of the edge surface finish has a major effect on the edge formability of the materials. The work also found that the variations in the edge forming performance are mainly the result of the influence of machining induced edge surface defects. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=titanium%20alloys" title="titanium alloys">titanium alloys</a>, <a href="https://publications.waset.org/abstracts/search?q=hole%20expansion%20test" title=" hole expansion test"> hole expansion test</a>, <a href="https://publications.waset.org/abstracts/search?q=edge%20formability" title=" edge formability"> edge formability</a>, <a href="https://publications.waset.org/abstracts/search?q=non-conventional%20machining" title=" non-conventional machining"> non-conventional machining</a> </p> <a href="https://publications.waset.org/abstracts/110917/effect-of-machining-induced-microstructure-changes-on-the-edge-formability-of-titanium-alloys-at-room-temperature" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/110917.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">137</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">408</span> Effect of Gas-Diffusion Oxynitriding on Microstructure and Hardness of Ti-6Al-4V Alloys</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Dong%20Bok%20Lee">Dong Bok Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=Min%20Jung%20Kim"> Min Jung Kim</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The commercially available titanium alloy, Ti-6Al-4V, was oxynitrided in the deoxygenated nitrogen gas at high temperatures followed by cooling in oxygen-containing nitrogen in order to analyze the influence of oxynitriding parameters on the phase modification, hardness, and the microstructural evolution of the oxynitrided coating.

It could be attained under the optimum oxygen partial pressure and temperature-time condition. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=titanium%20alloy" title="titanium alloy">titanium alloy</a>, <a href="https://publications.waset.org/abstracts/search?q=oxynitriding" title=" oxynitriding"> oxynitriding</a>, <a href="https://publications.waset.org/abstracts/search?q=gas%20diffusion" title=" gas diffusion"> gas diffusion</a>, <a href="https://publications.waset.org/abstracts/search?q=surface%20treatment" title=" surface treatment"> surface treatment</a> </p> <a href="https://publications.waset.org/abstracts/65271/effect-of-gas-diffusion-oxynitriding-on-microstructure-and-hardness-of-ti-6al-4v-alloys" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/65271.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">317</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">407</span> Synthesis of Bimetallic Ti-Fe-SBA-15 Using Silatrane</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ratchadaporn%20Kaewmuang">Ratchadaporn Kaewmuang</a>, <a href="https://publications.waset.org/abstracts/search?q=Hussaya%20Maneesuwan"> Hussaya Maneesuwan</a>, <a href="https://publications.waset.org/abstracts/search?q=Thanyalak%20Chaisuwan"> Thanyalak Chaisuwan</a>, <a href="https://publications.waset.org/abstracts/search?q=Sujitra%20Wongkasemjit"> Sujitra Wongkasemjit</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Mesoporous materials have been used in many applications, such as adsorbent and catalyst. SBA-15, a 2D hexagonal ordered mesoporous silica material, has not only high specific surface area, but also thicker wall, larger pore size, better hydrothermal stability, and mechanical properties than M41s. However, pure SBA-15 still lacks of redox properties. Therefore, bimetallic incorporation into framework is of interest since it can create new active sites. In this work, Ti-Fe-SBA-15 is studied and successfully synthesized via sol-gel process, using silatrane, FeCl3, and titanium (VI) isopropoxide as silica, iron, and titanium sources, respectively. The products are characterized by SAXD, FE-SEM, and N2 adsorption/desorption, DR-UV, and XRF. <p class="card-text"><strong>Keywords:</strong> <a
