摘　　要：研究了用有机多膦酸盐(HEDP)作络合剂,ZNP作添加剂电镀光亮锌镍合金,探讨了络合剂、氯化物含量[、Zn2+]/[Ni2+]比、阳极电流密度、温度、辅助络合剂对合金中镍含量的影响,测定了合金镀层中物相组成及镀液稳定性,通过筛选得出最佳最镀光亮锌镍合金的镀液组成及工艺条件,并讨论了锌镍合金的异常共沉积机理。In this paper, the electroplating of bright Zn-Ni alloy process was studied, the effect of （（1-hydroxy ethylidene） diphosphonate） acid （abbreviated as HEDP） coordinating agent, chloride content, [Zn^2＋]/[Ni^2＋] mole ratio, cathode current density, temperature, a class of aldehyde compound （abbreviated as ZNP additive agent） and supplementary coordinating agent on Ni content, and brightness of plating layer was discussed, the physical phase of alloy plating layer and stability of plating solution were determined. The optimum composition of plating solution for bright Zn-Ni alloy elcctroplating and technological condition was screened out and abnormal joint deposition mechanism was discussed.
