摩擦界面内杂质颗粒物的力学行为研究进展*

摩擦界面内夹杂的固体颗粒物，会影响摩擦副的摩擦、磨损性能，并可能导致摩擦副异常振动和温度升高，应用表面织构可改善摩擦界面的摩擦学特性，为摩擦副的减摩、抗磨提供了有效的途径。介绍摩擦界面夹杂有固体颗粒时的摩擦、磨损机制，概述颗粒-摩擦副的力学模型、颗粒被卷吸进入摩擦接触界面前后的力学行为，以及颗粒存在时表面织构的作用。展望颗粒-摩擦副系统的研究方向,包括非球形颗粒的力学行为研究，摩擦接触界面间颗粒的运移规律研究，摩擦体系各要素间的协同作用和制约机制研究，润滑脂作为润滑剂时固体颗粒的力学行为研究等。

Research Progress of Mechanical Behaviour of Particles in Frictional Interfaces

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.
