摘　　要：　选取影响电镀Zn Ni P合金的6个工艺参数,设计了L25(56)正交试验方案,探讨了镀液组成和电镀制度对Zn Ni P合金镀层性能的影响,用极差法分析了各工艺参数对镀层性能影响的显著性并确定了最佳工艺条件。优化验证实验结果表明:该工艺稳定,得到光亮、致密、外观平整的Zn Ni P合金镀层,得到的锌镍磷合金镀层的耐蚀性优于锌镍合金,且其耐蚀性随镀层中磷含量的增大而提高。A group of orthogonal text is arranged and carried out to study the effect on electroplating technology of Zn-Ni-P alloy, the range analysis is employed to distinguish the influent degree of factors include in this text, the optimum technology of Zn - Ni -P alloy electroplating is ensured. The test results on optimum condition show that technique is stable and the deposit layer is bright, fine and better performances. Corrosion resistance of Zn - Ni -P alloy deposits is superior to that of Zn - Ni alloy .
