摘　　要：某些金属在空气中摩擦时生成的润滑性氧化膜由于具有低摩擦系数、高耐磨性和自修复等特点越来越受到关注。摩擦过程中氧化膜的生成速度超过磨损速度是获得有效润滑的必要条件。摩擦氧化的动力学机制不同于热氧化，本文基于致密氧化膜的抛物线生长模型研究了摩擦状况下的氧化膜生长规律，使之尽早获得推广应用。The oxide films generated under friction condition are paid more and more attention to for its low friction coefficient, good wear resistance and self repairing characteristics, and effective lubrication is based on the fact that the growing rate of the oxide film is higher than its wearing rate. The mechanism of tribo oxidation is different from that of thermo oxidation in the dynamic aspect. It has great practical value to study the production rate of oxide under the friction condition for the application of the self producing lubricating oxides in industries. This paper presents an primary analysis of the mechanism of enhancing oxidation rate caused by rubbing based on the parabolic growing law of compact oxide films.
