摘　　要：自润滑耐磨复合材料涂层有良好的减磨耐磨性能,在材料的表面改性研究领域中发挥着巨大作用。为了使钛合金在使用寿命上能够获得较大程度的提升,利用激光熔覆技术向钛合金基材表面加入一定固体润滑剂和增强相颗粒,制备出的钛合金自润滑耐磨涂层可以显著提高涂层的耐磨性能以及减摩性能。基于国内外研究钛合金复合材料涂层的研究现状,阐述了钛合金表面耐磨复合材料涂层和自润滑涂层的耐磨损强化机理,讨论了自润滑涂层和耐磨涂层的材料选取方式。结果表明,新型固体润滑剂不仅可以降低材料表面的摩擦系数,而且因自身的化学惰性、适应能力强以及对环境污染小等特点,避免了传统润滑剂(润滑油、润滑脂)存在的缺陷;金属基陶瓷复合材料的综合性能更加显著,弥补了单一硬质相颗粒的不足,可作为耐磨涂层的重要组分。最后展望了该涂层未来的发展前景。Self-lubricating wear resistance composite coating has good wear reduction and wear resistance and plays a huge role in the field of surface modification research.In order to greatly improve the service life of titanium alloy,a certain amount of solid lubricant and enhanced phase particles are added to the surface of the titanium alloy substrate,the prepared self-lubricating wear resistant coating of the titanium alloy can significantly improve the wear resistance and friction reduction.Based on the research status of titanium alloy composite coating,wear resistance strength mechanisms of the titanium alloy wear resistant composite coating,self-lubricating coating are stated,the wear resistance composite coating and self-lubrication coating material selection are discussed.It is also concluded that the new solid lubricant can not only reduce the coefficient of friction on the material surface,but also break the defects of the traditional lubricant(lubricating oil,lubricating grease)due to its own inactive chemical properties,strong adaptability,and small environmental pollution.The comprehensive properties of the metal-based ceramic composites are more significant,compensating for the deficiency of a single hard phase particle,and can be used as an important component of the wear-resistant coating.The future development prospect of the coating is expected.
