摘　　要：本文利用销-盘法摩擦磨损试验,考察磨接触面处相变层的组织形貌,分析其形成的机理。考察实验应力和摩擦速度对相变层深度的影响。结果表明,摩擦磨损试验中接触面温度普遍超过了奥氏体相变临界点,相变层中的白层为坚硬且不易被腐蚀的胞状组织,相变层深度随着应力和摩擦速度的增加而增加。In this paper,author use the pin-on-disk method to investigate the microstructure and the formationmechanism of phase transformation layer.The influence of the experimental stress and the friction velocity on thedepth of the phase transformation layer is investigated.The results show that the friction surface temperature hadexceeded the austenite phase lower critical solution temperature.The white phase transformation layer is hard andcorrosion resistant cellular structure.The phase transformation layer depth increases with the increase of stress andfriction velocity.
