摘　　要：为了制备色泽纯正的仿金层,且满足工艺操作简单、对环境污染小的要求,采用化学镀镍与化学浸镀仿金相结合的方法在A3钢表面制备仿金层,探讨了化学浸镀仿金液的组成、温度及施镀时间对仿金层色泽和附着力以及仿金液稳定性的影响。结果表明:最佳工艺为6～8g/LSnSO4,5～8g/LCuSO4.5H2O,10～20g/L配位剂,10～25mL/LH2SO4,5～10mL/L稳定剂,温度15～35℃,时间3～5min;仿金镀层色泽均匀,装饰效果好,且工艺操作简单,镀液无毒,对环境污染小。Electroless nickel plating technique was combined with electroless imitation gold plating technique to prepare gold-imitation layer on A3 steel. The effects of the composition of gold-imitation bath, temperature and time on the color and adhesion of gold-imitation layer and stabili-ty of gold-imitation bath were investigated. As the results, the optimized bath for electroless imitation gold plating was composed of 6～8 g/L SnSO4,5 ～8 g/L CuSO4·5H2O, 10～20 g/L che-lating agent, 10～25 mL/L H2SO4 and 5～10 mL/L stabilizer, and the optimized temperature and time were 15～35 ℃ and 3 ～ 5 min respectively. The resulting gold-imitation layer had uniform color and good decoration efficacy as well. Moreover, the tech-nology had advantages of simple operation, non-toxic bath and little environmental pollution.
