摘　　要：基于三体摩擦体系,综述了摩擦第三体理论研究的发展与现状。第三体由存留在摩擦表面的磨损粒子构成,其形态、运动方式与材料成分和摩擦条件密切相关,从而影响材料的摩擦磨损性能。第三体具有颗粒区和压实区两种形貌,二者处于相互转化的动态过程并起到转移载荷的作用;第三体的4种运动方式对第一体起到速度协调的作用;第三体流量循环的构建有助于理解材料的磨损特性。这些机构的揭示为认识材料的摩擦磨损性能奠定了基础。The present paper reviewed recent research works and achievements in tribology based on the third body system. The third body is formed by wear debris existing on the friction surface, and its formation and motion are related to the compositions and friction conditions. The third body appears to possess two distinctive morphologies, particles and compact zone, which transform into each other dynamically, leading to transfer of load. The four modes of motion of the third body accommodate the velocity of the first body. The study of the tribological behaviour of the third body would facilitate the understanding of wear mechanisms. These frameworks lay the foundation to comprehending friction and wear properties of materials.
