摘要

摘要: 采用三点接触式摩擦机对钢/钢配副在不同滑滚比（SRR）以及边界润滑条件下的表面摩擦特性进行了研究，使用光学显微镜和扫描电子显微镜（SEM）对摩擦副表面不同疲劳磨损阶段的损伤形貌进行表征，并利用X射线电子光谱仪（XPS）对摩擦副表面进行了化学分析。结果表明：提高滑滚比可以减少摩擦副表面微点蚀的数量，磨损量也随之上升，而摩擦系数没有明显的变化。同时，XPS结果表明：随着滑滚比的提高，摩擦副表面所含氧化物含量上升，而润滑油膜随之变厚。因此，滑滚比影响摩擦副在边界润滑条件下的摩擦学性能不仅与摩擦系数和磨损量有关，也与其中的摩擦化学有紧密联系。

Abstract: An automation test rig using the proven three point contact configuration was applied to studying the effect of slide to roll ratio (SRR) on the tribological behavior of lubricated steel/steel contacts in a boundary lubrication regime. The tested specimen surface was examined under an optical microscope and a scanning electron microscope (SEM) to study the fatigue behavior of the specimen surface. Then the X-ray photo-electronic spectroscope (XPS) is applied to studying the related tribochemistry behavior. The study results show that the increase of SRR can reduce the number of micropits on the worn surface, while wear increased and friction did not change much. XPS study results indicate that the increase of SRR resulted in the increase of oxide concentration on the worn surface as well as the film thickness. Therefore, the effect of SRR on the tribological behavior of lubricated steel/steel contacts in the boundary lubrication regime is not only related to friction and wear but also highly depends on related tribochemistry.
