摘　　要：结合磨损试验得到的磨损率曲线,采用扫描电子显微镜对T8钢干滑动磨损表面和磨损颗粒进行了观察分析。指出在1～2m/s的滑动速度范围、20～140N的正向载荷条件下,T8钢的干滑动磨损过程主要有氧化特征的轻微磨损和有粘着脱层特征的严重磨损两种主导机制,并在较高的载荷和速度时开始出现熔化磨损特征。In this payer, the dry sliding worn surfaces and wear particles of steel T8 are studied by SEM in combination with the analysis of wear rate. The results indicate that the dry sliding wear of steel T8 involves two kinds of characteristic wear mechanisms (oxidationdominated mild wear and adhesion-dominated revere wear), when the speed is in the range of 1.0～2.0 m/s and the load is in the range is of 20～140 N. The characteristics of melting-dominated wear, however, will occur with still greater load and speed.
