　　摘要 在鎳磷化學鍍的基礎上，研究了微米、納米金剛石化學復合鍍工藝。采用正交試驗方法，研究化學鍍液、金剛石種類與濃度、表面活性劑種類與含量以及熱處理溫度等因素對鍍層顯微硬度的影響。結果表明：對鍍層硬度影響明顯的因素依次為金剛石種類、表面活性劑種類、熱處理溫度和表面活性劑含量，而鍍液種類和金剛石濃度對鍍層硬度的影響較小。最佳工藝為：金剛石為納米金剛石灰粉，添加陰離子表面活性劑，熱處理溫度為350oC，表面活性劑含量為1：10，選用化學鍍液B，金剛石濃度為6.0g/L.(金剛石與磨料磨具工程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 concentration 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，sort 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 surfactant，heat treatment temperature being 350 oC，the content of surfactant being 1：10，using the electroless plating bath B，and the concentration of nanodiamond being 6.0 g／L．
