摘　　要：采用可溶性镍阳极电刷镀方法,在铜片上制备了Ni–P纳晶镀层和Ni–P–SiC复合镀层,镀层表面平整、致密、无裂纹。纳米颗粒的加入没有改变镀层的纳米晶结构,对镀层磷含量影响不大。硬度测试和摩擦磨损试验表明:纳米SiC的加入起到细晶强化和弥散强化作用,可以提高镀层的硬度和耐磨性能;添加纳米颗粒后镀层磨损方式由黏着磨损转变为磨粒磨损。Nanocrystalline Ni-P and Ni-P-SiC coatings were produced on Cu substrates by electro-brush plating using a soluble Ni anode. The coatings were smooth, compact, uniform and free of cracks. The nanostructure of the coating remains unchanged by the addition of nano-sized ceramic particles and the P content of the coating is slightly reduced. The tests of hardness and wear resistance indicated that the addition of nano-SiC particles leads to a strengthening of coatings through grain refinement and dispersion, which help to improve the hardness and wear resistance of coating. After nano-particles are added, the wear mechanism of Ni-P-SiC coatings is transformed from adhesive wear to abrasive wear.
