摘　　要：采用正交实验法,对铜表面电沉积镍基纳米ZrO2复合镀层的工艺进行了研究,观察了复合镀层的表面及截面形貌,并对其耐磨性能进行了测试分析。所涉及实验条件下的最优工艺为:阴极电流密度4A/dm2,镀液温度60℃,极间距为12cm。采用此最优工艺条件,得到了晶粒细小,表面平整、光滑,显微组织致密、均匀的Ni-ZrO2纳米复合镀层,且复合镀层的显微硬度比纯镍镀层有明显提高。Nickel nano-ZrO2 composite coatings electrodeposition process were studied by orthogonal test method in the copper. Besides, the surface and the section morphology of the composite coating were also observed, wear resistance of the composite coating was analyzed. The optimized technological conditions are cathode current density： 4 A/ dm2 , the bath temperature： 60 ℃ , the distance between two electrodes： 12 cm. In this optimum process conditions get a flat morphology and compact microstructure Ni-ZrO2 nano-composite coating, and its micro-hardness is remarkably improved compared to pure nickel plating.
