Study on the Tribological Properties of Composite Coating-Textured Titanium Alloy
摘要 摘要：钛合金是航空航天机械零部件的重要原材料，但钛合金/不锈钢配副中，钛合金其耐磨性差，摩擦系数高且不稳定。表面织构技术和复合涂层技术是提高表面摩擦学性能的有效途径。本研究结合表面织构技术和复合固体润滑涂层技术对TC4(Ti-6Al-4V)进行表面改性，探究了表面改性后钛合金与不锈钢之间的摩擦学行为。试验结果表明，表面织构与固体润滑涂层的耦合作用可以显著改善钛合金的摩擦学性能。

Abstract ：Abstract: Titanium alloy is an important raw material for aerospace machinery parts, but among titanium alloy/stainless steel pairs, titanium alloy has poor wear resistance, high friction coefficient and unstable. Surface texture technology and composite coating technology are effective ways to improve surface tribological properties. This study combined surface texture technology and composite solid lubricating coating technology to modify the surface of TC4 (Ti-6Al-4V), and explored the tribological behavior between titanium alloy and stainless steel after surface modification. The test results show that the coupling effect of surface texture and solid lubricating coating can significantly improve the tribological properties of titanium alloys.
