光亮剂对化学镀镍磷合金镀层的影响

The Influence of Brightener on the Electroless Plating Ni-P Alloy Coatings

为了优化酸性化学镀Ni-P镀液中光亮剂的配方,运用试验方法确定了复合光亮剂的最佳成分配比,通过对不同光亮剂条件下镀层宏观形貌的观察与分析,结果表明:1000mL镀液中,添加12mL CdSO4、12.5mL C4H6O2、23mL C12H25NaO3S的复合光亮剂进行施镀,可得到镜面光亮的镀层,镀层中晶粒尺寸呈纳米尺度。

In order to optimize the brightener in acidic electroless Ni-P plating electrolyte, the optimum composition mach ratio was determined by experiment method. The coating＇s macro-morphology prepared under deferent brightener also was observed and analyzed. It was indicated that the coatings with mirror-like surface and nano-meter scale grain could be obtained while adding 12mL CdSO4, 12.5mL C4H6O2 and 23mL C12H25NaO3S into the plating electrolyte.
