摘　　要：针对近年来钛及钛合金表面气体元素扩散耐磨处理技术的研究进展进行了总结梳理。认为对钛合金表面进行渗氧、渗氮和渗碳耐磨处理,都可以起到提高表面硬度,改善表面耐磨性能的效果,结合真空和等离子体等技术,可以使得扩散层厚度增加,但需要结合工艺选择恰当的参数,不然会对材料力学性能带来较大的影响。另外耐磨状态是多样的,没有一种耐磨层能够适合于所有的摩擦环境;同时现代的服役环境更趋于复杂,不仅要求耐磨,还有耐蚀、导电等其它功能方面的要求,这样,就需要材料表面设计者,依据服役的苛刻条件,结合多场的相互作用关系,在现有表面技术的基础上设计和创新。In this paper,the resent research progress of gas element diffusion wear treatment technology on surface of titanium and titanium alloy is summarized.It is believed that treatment technology of oxidizing,nitriding and carburizing on the surface of titanium alloy,can improve its surface hardness and wear resistance.In addition,the combination of vacuum and plasma technologies can increase the thickness of the diffusion layer,but appropriate parameters need to be selected in combination with the process,otherwise it will have a greater impact on the mechanical properties of the material.Furthermore,because the wear-resistant environment is diverse,the wear-resistant layer is difficult to adapt to all friction environments.Modern development has made the service environment of materials more complex.It requires not only wear resistance,but also corrosion resistance,electrical conductivity and other functional requirements.In this way,the material surface designer is required to design and innovate on the basis of the existing surface technology based on the harsh conditions of service and the interaction of multiple fields.
