摘　　要：在合理选择化学镀Ni-P合金配方和工艺条件的基础上,研究了稳定剂KI、Pb(Ac)2和Na2S2O3对化学镀Ni-P合金镀液的稳定性、镀速以及镀层硬度、孔隙率、耐蚀性能等的影响。结果表明:KI的最佳加入量为8mg/L,稳定剂Pb(Ac)2在用量为1mg/L效果也较好,而Na2S203浓度应小于2mg/L,但是稳定剂KI的综合效果要优于Pb(Ac)2、Na2S2O3。By using the experiment method of bath solution stability,depositing velocity,porosity rate and corrosion resistance test, the effect of KI,Ph（Ac）2 and Na2S2O3 stabilizers on the properties of Electroless Ni-P alloy is studied. The experimental results indicate： the optimum additive of KI was 8 mg/L and that of Pb （Ac）2 is 1 mg/L.The addition of Na2S2O3 should be lower than 2mg/L.The effect of KI stabilizer was better than Pb （At）2 and Na2S2O3.
