摘要
对低合金钢基体化学沉积镍磷镀层的微动磨损特性进行了研究。根据摩擦系数、磨损量的变化规律和磨损表面形貌特征，讨论了镀层微动磨损机理及热处理对微动磨损性能的影响。室温、大气条件下的试验结果表明：热处理只影响磨损的程度，不能改变磨损的机理；镀层厚度２５μｍ，经３５０℃×２ｈ回火，可具有较好的耐微动磨损性能。
The fretting wear characteristics of the electroless nickle deposits based on a low alloy steel substrate have been studied. According to the analysis on the friction coefficient, wear volume and wear morphology the mechanism of the fretting wear and the influences of the heat treatment on the fretting wear were analysed. The results of the tests carried out at the ambient temperature in the air indicated that the deposits undergone heat treatment at 350℃ for two hours would only affect the level of wear, not the wear mechanism, and would improve the fretting wear properties.
