Abstract

The need for titanium and its alloys has led to a significant increase in commercial manufacturing, although this material’s poor tribological qualities have been a drawback. The present study was to determine the effect of laser-textured surfaces to enhance Ti6Al4V surface wear performance. The sample underwent laser texturing based on pre-set parameter values at 15 W power at a laser scanning speed of 200 mm/s with a frequency of 50 kHz. The surface morphological and topological profile of laser-textured Ti6Al4V was characterized with also the surface microhardness. A comparative appraisal of wear rate (WR) and coefficient of friction (COF) for related samples of as-received Ti6Al4V and laser-textured Ti6Al4V was performed under dry and oil sliding conditions. The results revealed that the formation of oxidation due to the frictional force and plastic displacement plays a role of abrasive to the laser-textured surface and may result in increasing the COF. The wear rate of the laser-textured surface of Ti6Al4V exhibited 88.31% improvement compared to the as-received Ti6Al4V in the dry sliding wear test. It was proved that Ti6Al4V could benefit from LST to gain effectively enhanced wear performance.

Ti6Al4V激光织构表面对摩擦磨损性能的影响

对钛及其合金的需求导致了商业制造的显著增加，尽管这种材料的摩擦学质量差是一个缺点。本研究旨在确定激光织构表面对Ti6Al4V表面磨损性能的影响。在15 W功率下，激光扫描速度为200 mm/s，频率为50 kHz，根据预先设定的参数值对样品进行激光纹理处理。对激光织构Ti6Al4V的表面形貌、拓扑形貌及表面显微硬度进行了表征。在干滑和油滑两种条件下，对接收态Ti6Al4V和激光织构Ti6Al4V相关样品的磨损率(WR)和摩擦系数(COF)进行了对比评价。结果表明，由于摩擦和塑性位移引起的氧化对激光织构表面起磨料作用，可能导致COF的增加。在干滑动磨损试验中，激光织构Ti6Al4V表面的磨损率比原位Ti6Al4V提高了88.31%。实验证明，LST可以有效提高Ti6Al4V的磨损性能。
