摩擦系统的复杂性和影响因素的多样性使摩擦学理论远落后于工业的需求.本文回顾并从统计热力学熵的角度讨论了摩擦的本质,分析了摩擦磨损研究的方法和摩擦体系热力学研究的现状.认为熵能够成为表述摩擦磨损过程演变的主参量,熵平衡方程可望作为摩擦学理论的基石.展望摩擦体系的非平衡态热力学在摩擦学相关领域的应用前景.
The complexity of the friction system and the diversity of influencing factors make the theory of tribology far behind the needs of industry.This paper reviews and reviews the essence of friction from the perspective of statistical thermodynamic entropy and analyzes the research methods of friction and wear and thermodynamics of friction system It is considered that entropy can be the main parameter to describe the evolution of friction and wear process, and the entropy equilibrium equation is expected to be used as the cornerstone of tribological theory.The prospect of the application of non-equilibrium thermodynamics in tribology is forecasted.
