摘　　要：目的优化中温化学镀镍三元络合剂体系,得到性能优良的化学镀镍层。方法选取乳酸、冰乙酸及柠檬酸作为络合剂组分,以镀速和含磷量为考察指标,通过设计L9(34)正交实验,研究次亚磷酸钠、乳酸、冰乙酸及柠檬酸的浓度对化学镀镀速以及镀层磷含量的影响。结果综合考虑镀速和磷含量,得到的最佳三元络合剂体系为20 mL/L乳酸+15 mL/L冰乙酸+10 g/L柠檬酸,该条件下镀速为6.4 mg/h,镀层磷质量分数为8.8%。结论采用优化的络合剂体系,可以获得致密均匀、结合力良好的化学镀镍层。Objective In order to obtain Ni-P coating with excellent performance, the ternary eomptexing agent for medium tem- perature was optimized. Methods By selecting lactic acid, glacial acetic acid and citric acid as eomplexing agents, using plating speed and phosphorus content as evaluation indicators, the effect of sodium phosphate, lactic acid, glacial acetic acid and citric acid concentration on the plating speed and phosphorus content was studied through designing L9（3^4） orthogonal experiments. Re- suits Considering the plating rate and phosphorus content, the optimal ternary complexing agent system was determined as follows： lactic acid 20 mL/L, glacial acetic acid i5 mL/L and citric acid 10 g/L. The plating speed was 6.4 milligram per hour and phos- phorus contertt was 8.8wt% in this optimal system. Conclusion The results showed that even and compact Ni-P coating with good adhesion couid be obtained in the optimized complexing agent system.
