摘要 在镍磷化学镀的基础上，研究了微米、纳米金刚石化学复合镀工艺。采用正交试验方法，研究化学镀液、金刚石种类与浓度、表面活性剂种类与含量以及热处理温度等因素对镀层显微硬度的影响。结果表明：对镀层硬度影响明显的因素依次为金刚石种类、表面活性剂种类、热处理温度和表面活性剂含量，而镀液种类和金刚石浓度对镀层硬度的影响较小。最佳工艺为：金刚石为纳米金刚石灰粉，添加阴离子表面活性剂，热处理温度为350oC，表面活性剂含量为1：10，选用化学镀液B，金刚石浓度为6.0g/L.(金刚石与磨料磨具工程2009年第一期)

Abstract On the basis of electroless Ni-P plating，the techniques of electroless Ni-P-diamond composite plating were studied．The effect of electroless plating solution，the sort and concentra螺纹接头tion of diamond，the sort and content of surfactant and heat treatment temperature on the micro—hardness of coating was studied through orthogonal design．Results show that the factors affecting the hardness of coating are，in order of significance，sort of diamond，s风批ort of surfactant，heat treatment temperature and content of surfactant．The effect of sort of electroless plating solution as well as the concentration of diamond is slight．The optimal parameters for the best hardness of plating are suggested as，adding nanodiamond and anionic surfactan金昌t，heat treatment temperature being 350 oC，the content of surfactant being 1：10，using the electroless plating bath B，and the concentrat项链ion of nanodiamond being 6.0 g／L．
