摘　　要：钛合金因具有高比强度、高比模量、耐腐蚀、耐低温、无磁等性能特点而被广泛应用。然而,与传统钢铁材料相比,钛合金存在弹性模量低、耐热性能不足、耐磨性差等局限,阻碍其在航空航天、兵器行业等领域的推广应用。与钛合金相比,钛基复合材料可将基体钛合金高强塑性与增强体高模量、高耐磨的优势相结合,具有比钛合金更高的弹性模量、耐磨性及高温性能,从而满足一些高承载、抗冲击、高耐磨和高温抗氧化等极端工况条件下的使用要求。从钛基复合材料发展历程出发,对钛基复合材料耐磨性研究进展加以概述,主要介绍了钛基复合材料耐磨性表征方法和摩擦磨损行为,对钛基复合材料良好耐磨性能、高耐磨钛基复合材料的设计及TMCs表面耐磨改性技术进行阐述,最后进行总结与展望。Titanium alloys are widely used because of their excellent comprehensive properties such as high specific strength,high specific modulus,corrosion resistance,low temperature resistance,and nonmagnetism.However,compared with traditional steel materials,titanium alloys have limitations such as low elastic modulus,insufficient heat resistance and poor wear resistance,which hinder their promotion and application in the aerospace,weapon and other industries.Compared with titanium alloys,titanium matrix composites can combine the advantages of high-strength plasticity of the matrix titanium alloy and the high modulus and high wear resistance of the reinforcement.Titanium matrix composites have higher elastic modulus,wear resistance and high-temperature performance than titanium alloys.It meets the requirements of extreme working conditions such as high load,impact resistance,high wear resistance and high temperature oxidation resistance.Starting from the development history of titanium matrix composites,this paper summarized the research progress on wear resistance of titanium matrix composites,and the characterization methods of wear resistance,friction and wear behaviors of titanium matrix composites were also introduced.The good wear resistance mechanism of titanium matrix composites,the design of high wear-resistance titanium matrix composites and wear resistant surface modification technology were also described.
