摘　　要：镀镍层内应力是影响镀镍层质量的重要因素,介绍了一种镀镍层内应力的测试方法,通过设计正交试验,分析了氨基磺酸盐电镀镍层内应力的影响因素;优选了氨基磺酸盐镀镍的工艺,并探究了NiCl_2·6H_2O含量、pH、温度、电流密度及添加剂对镀层内应力的影响,为槽液的维护和镀层改善提供了参考。Internal stress is a crucial factor for the quality of nickel electrodeposition. A measuring method for the internal stress of nickel aminosulfonate electrodeposition was described and the influence factors of internal were analyzed by orthogonal test. Process conditions of aminosulfonate electrodeposition technolo- gy were optimized, effects of nickel chloride content, pH value, temperature, current density as well as additive on the internal stress of the coatings were also investigated. A reference about maintaining bath solution of nickel electrodeposition and improving nickel plating was provided.
