摘　　要：利用纳米高岭土的纳米级别采用纳米复合电镀技术对FeCoNi镀层的耐磨性能进行提高,探究了复合电镀的最佳工艺参数,对电流密度和温度进行了确定。采用SEM对镀层和磨痕的表面形貌进行分析,通过摩擦磨损试验对镀层的耐磨性进行分析。结果表明,最佳的铁钴镍-纳米高岭土(FeCoNi-Nanokaolin,FeCoNi-Nk)复合电镀涂层的工艺参数为:温度55℃、电流密度为15 A·dm^(-2)、纳米高岭土浓度为0.5 g·L^(-1)、搅拌速度为200 r·min^(-1)、pH=5。镀层的磨损量和摩擦系数都减小了,FeCoNi-Nk复合镀层的耐磨性有显著提高。The wear resistance of FeCoNi coating was improved by nanocomposite electroplating technology using Nano-kaolin,the optimal process parameters of composite electroplating were explored,and the current density and temperature were determined.The surface morphology of the coating and wear marks were analyzed by SEM,and the wear resistance of the coating was analyzed by friction and wear test.The results showed that the optimal process parameters of the composite electroplating coating were as follows:temperature 55℃,current density 15 A·dm^(-2),concentration of nano-kaolin 0.5 g·L^(-1),stirring speed 200 r·min^(-1),pH=5.The wear and friction coefficient of FeCoNi-Nk composite coating decreased,and the wear resistance of FeCoNi-Nk composite coating increased significantly.
