摘　　要：为了防止钢表面酸性电镀铜出现置换铜,采取在电镀铜前增加化学镀镍工序,研究了化学镀镍工艺对酸性电镀铜的影响。结果表明,化学镀镍时间超过6 min时(镍层厚度>2.5～3μm),工件在酸性镀铜液中浸泡10 min,无置换铜出现。化学镀镍层对后续的酸性镀铜层的表面形貌和附着力均无明显影响,表明化学镀镍可作为钢酸性镀铜的底层。In order to avoid copper replacement reaction during sulfate copper electroplating on steel surface, electroless nickel plating process was introduced as the pretreatment of electroplating. The effect of electroless nickel plating on sulfate copper electroplating was studied. The results show that there is no copper precipitation on the surface of steel samples electroless nickel plated at least for 6 min after dipping in sulfate copper electroplating solution for 10 min. The effects of electroless plating coating on the both the surface appearance and the adhesion of copper coating are not obvious, so the eleetroless nickel plating can be used for the pretreatment of sulfate copper electroplating.
