摘　　要：载流摩擦磨损是摩擦副在有电流通过时的接触行为。载流摩擦副在工作过程中受力、电、热等多种因素耦合作用,损伤机制复杂多变。综述载流摩擦中的摩擦磨损机制,重点分析服役工况对载流摩擦磨损性能和导电性能的影响,阐述电弧产生的原因及影响因素,并对载流摩擦中的温度场及其仿真模拟研究成果进行归纳,总结载流摩擦材料的应用现状。概括载流摩擦的研究现状及其存在的问题,并指出未来应加强接触副材料在多环境下、多因素耦合作用下的摩擦磨损行为和失效机制研究,并有针对性地研发新型复合材料,以满足具体的工作条件和特殊的性能要求。The current-carrying friction and wear refers to the contact behavior of friction pair when the current passes through.The damage mechanism of the current-carrying friction pair is complicated and changeable due to the coupling action of force,electricity and heat.The friction and wear mechanism of current-carrying friction was reviewed,the influence of service conditions on current-carrying tribological properties and conductivity was analyzed,the arc generation causes and influencing factors were expounded,the temperature field in current-carrying friction and its simulation research results,and the application status of current-carrying friction material were summarized.The research status and existing problems of current-carrying friction were generalized.It was pointed out that the research on the friction and wear behavior and failure mechanism of contact pair materials under multi environment and multi factor coupling should be strengthened in the future,and new composite materials should be developed to meet the specific working conditions and special performance requirements.
