摘　　要：研究了氯化钠型锌镍合金镀液与镀层的性能。以氯化钠替代氯化钾作导电盐 ,仍选用 XA-88A添加剂 ,通过对其镀液性能和镀层性能的测试 ,以及对电流密度、温度等因素对合金成分与镀层耐蚀性能影响的讨论 ,证明氯化钠型锌镍合金镀液和镀层性能接近氯化钾体系的最佳水平 ,从而对保证生产质量 ,降低生产成本提供了技术准备。The Zinc- Nickel alloy coatings and bath solution in the Na Cl system are studied,By means of using Na Cl asan electric conductive saltin the place of KCl.The propertiesof coatingsand bath solution are tested by using XA- 88A additive.Besides,there are also discussed the dffects of currentdensity and temperature on the composition of the alloy and the corrosion resistance.The results show thatthe properities of coatings and bath solution in the Na Clsystem approach the state of thatin the KCl system.This providesthe technicalpossibility for reducing production costs while keeping the original production qualities.
