摘　　要：钛合金具有高的比强度、抗疲劳强度和抗腐蚀性能,但其表面硬度及抗磨损性能较差,提高其抗磨损性能一直是研究的热点。对改善钛合金的抗磨损性能的研究主要分为表面处理和整体处理两种方法。表面处理主要通过在钛合金的表面形成具有特殊作用的涂层或加工硬化层以提高其表面抗磨损性能;整体处理主要通过加入或合成具有高硬度的陶瓷成分强化基体以改善材料整体的抗磨损性能。两种处理方法对钛合金的强化机制相似,但整体处理方法对钛合金在苛刻条件下的应用更具有工程实际意义。Titanium alloy has high specific strength, fatigue strength and corrosion resistance, but its surface hardness and wear resistance are poor, improving its wear resistance has been a research hotspot. The research on improving the wear resistance of titanium alloy can be divided into two methods: surface treatment and integral treatment. Surface treatment is mainly through the formation of a special coating or work hardening layer on the surface of titanium alloy to improve its wear resistance;The overall treatment is mainly through adding or synthesizing ceramic components with high hardness to strengthen the matrix to improve the overall wear resistance of the material. The strengthening mechanism of the two treatment methods is similar to that of titanium alloy, but the overall treatment method has more practical engineering significance for the application of titanium alloy under harsh conditions.
