使用激光处理设备对钛合金表面进行织构化处理,获取了间距为100μm 的规则等宽栅条表面,使用 MRTR 多功能摩擦磨损实验机在油浴条件下进行摩擦磨损实验,实验中对摩摩擦副与织构化表面的滑动角度分别为0,45和90°,使用 SEM 检测磨损后试样表面形貌。实验结果表明织构化表面与对摩摩擦副呈不同角度相对运动时,摩擦因数在稳定状态下的数值全部约为平滑表面摩擦因数的50％。而对摩角度为45和90°时织构化表面的摩擦特性优于对摩角度为0°时。其中尤以对摩角度为90°最佳。

The titanium alloy surface was texturing treated by laser processing equipment.The isometric grid with spacing of 100 μm was obtained.The friction and wear experiments were conducted by using the MRTR multi-functional friction and wear tester in oil bath condition.The sliding angle of the friction pair and textured surface was 0,45 and 90°,respectively.The worn surface was detected by using SEM.The experimental results show that the friction coefficient of the textured surface are about half of the smooth surface in the steady state at every different sliding angles.The friction properties of the textured surface when the friction angle are 45 and 90°were better than friction angle was 0°.Especially the friction angle of 90°.
