铜镍复合化学镀

Study on Electroless Copper and Nickel Plating

摘要: 以甲醛为还原剂，ＥＤＴＡ为配位剂的碱性化学镀铜液中用添加Ｎｉ＾２＋，表面点缀镍和层状复合化学镀（镀镍、镀铜）三种方法优化了化学镀铜工艺条件，提高了不锈钢基化学镀铜层的性能。结果表明，几种方法都在不同程度上改善了不锈钢基化学镀铜层的耐磨损性能，添加Ｎｉ＾２＋与层状复合镀相结合的效果最好，镀层的耐磨损性能比一般化学镀铜层提高３５％左右。

Abstract: This work optimized the recipe of alkaline electroless copper plating with formaldehyde(37%) as reducing agent and EDTA as complexing agent by addition of Ni 2+ , surface embellishing nickel plating and layer compounding material of nickel and copper. It was showed that all three means raised the anti wear property of the film to varying degrees.
