摘　　要：研究了马氏体不锈钢化学镀Ni-P合金的工艺。讨论了中性化学镀镍过程中硫酸镍、次磷酸钠、柠檬酸三钠、温度对镀速的影响。获得的最佳工艺条件为:硫酸镍10g/L,次磷酸钠20g/L,柠檬酸三钠12g/L,85℃。在此条件下获得的镀层中磷的质量分数为10.19%,属于高磷镀层,镀层孔隙率低,均匀地覆盖在基体上。Electroless Ni-P alloy plating on martensite stainless steel was studied,and the effects of nickel sulfate,sodium hypophosphite,sodium citrate and temperature on the deposition rate were also discussed.The obtained optimum process conditions were determined as follows：nickel sulfate 10 g/L,sodium hypophosphite 20 g/L,sodium citrate 12 g/L and temperature 85 ℃.An alloy deposit with phosphorus element mass fraction of 10.19 % and featuring low porosity and well-distributed coverage was obtained under the optimum conditions.
