摘　　要：本文对化学镀Ni-P合金的工艺参数进行研究,确定了最佳工艺条件,采用扫描电镜、电子探针、X射线衍射仪对镀层的成分和组织结构进行分析,得到Ni-P非晶态合金层。试验表明:镀层在15%H2SO4和10%HCl溶液中,具有优良的耐蚀性,其外观有较好的光亮性。Technology parameters of electroless Ni - P alloy were investigated and optimum technical conditions were defined in this paper, The composition and structure of coating were analysed through scanning electron microscope, electron probe and xray diffractometer. The Ni-P amorphous alloy coating could be obtained. Test show that Ni-P coating has good corrosion resistance in 15%H2SO4 solution and 10%HC1 solution. The outward appearance of the coating is bright.
