摘要
研究了磨削加工、磨削表面经过跑合后和机械研磨后的表面形貌特征、固体接 触特性、润滑效应及摩擦特性。结果得出跑合和研磨不仅降低了表面粗糙度而且磨去了 表面轮廓上的尖峰使表面形貌分布发生偏斜，两者都对减少固体接触改善润滑性能及降 低摩擦有显著效果。对比分析还得出机械研磨与跑合有相似的作用，而研磨的作用更为 明显。
Ground, run--in and polished suface are dealt with in this paper, and their topography, contact properties, lubication and rubbing behaviours are studied. The results show that running-in or polishing not only reduces surface roughness but also wears the peaks on the surfaces to cause the skew in surface distribution, both are of benefit to decreasing asperity contact and friction and to improveing lubrication. It also shows that the effect of polishing is similar to and more obvious than the effect of running--in.
