摘　　要：研究了金刚石含量、表面活性剂及热处理温度等工艺因素对Ni-P-纳米金刚石灰粉复合镀层的摩擦磨损性能的影响,并对复合镀层的表面形貌及组织结构进行了分析。结果表明:添加爆轰纳米金刚石灰粉能提高复合镀层的耐磨性能。热处理温度与表面活性剂种类对金刚石灰粉复合镀层耐磨性能的影响最大,复合镀层耐磨性能最佳时的工艺参数为:金刚石灰粉含量为4 g/L,热处理温度为400℃,表面活性剂采用SHP,其含量为1:20。The effect of factors, such as nano-diamond content, type of surfactant, heat treatment temperature on the wear resistance of nano-diamond composite coating was studied. The surface morphology and the structure of composite coating were analyzed. Results show that the addition of the diamond gray powder in plating bath can improve the wear-resistance of coating. The optimal parameters are followed as： the nano〈liamond content of 4 g/L, heat treatment temperature of 400 ℃, adopted surfactant SHP and content of 1：20.
