摘　　要：对中温高磷化学镀镍镀液配方进行正交试验优化。在基本配方的基础上,研究了苯骈三氮唑(BTA)、丁二酸和硫酸高铈(Ce(SO4)2·4H2O)三种添加剂含量对镀速和磷含量的影响。在BTA 0.5mg/L,丁二酸0.07mol/L,Ce(SO4)2·4H2O 6mg/L添加剂浓度下进行中温高磷化学镀镍时效果最好,所得镀片光滑,硬度高,耐蚀性好,整体性能优良,镀层磷含量10.83%,镀速达7.02μm/h。通过对实验所得的镍磷合金镀层组织与性能的研究,为中温高磷化学镀镍工艺的开发提供了一定的借鉴。The additive compositions of middle-temperature and high-phosphorus eleetroless nickel-phosphorus alloy plating bath were optimized by orthogonal test.The effects of different additives content including benzotriazole(BTA),succinic acid,and cerium(IV)sulfate on deposition rate and phosphorus content of Ni-P coating were discussed.The optimal compositions of the three additivesare as follows:BTA 0.5 mg/L,succinic acid 0.07mol/L,and cerium(IV)sulfate 6 mg/L.Under the optimal formulation,the deposition rate of 7.02μm/h,and phosphorus content of 10.83%.The deposit is bright and level,high hardness,and good corrosion resistance.In sum,the integrated properties of coating is very excellent.The research on the structure and properties of the Ni-P alloy coating obtained from the experiment provides a reference for the development of the process of electroless nickel plating at medium temperature and high phosphorus.
