    Abstract:

    The solid particles entrained in the frictional interfaces will affect the friction and wear performance of contacting elements,and may lead to abnormal vibration and temperature rising.The application of surface texture can improve the tribological performance,and provide an effective way for friction reduction and wear resistance.The friction and wear mechanism of contacting interfaces which invaded by solid debris were introduced,and the mechanical model of the particle-friction pairs,the mechanical behaviour of the particles before and after entrapment,as well as the roles of surface texture when debris in the frictional interfaces were summarized.The research directions of particle-friction pairs are as follows:the research of mechanical behaviour of non-spherical particles,the research of migration law of particles,the research of mutual promotion and suppression relationship among the elements in the tribology system,and the research of mechanical behaviour of particles under grease lubrication conditions.
