| 摘 要： | 研究了EDTA体系无氰碱性镀铜电解液中络合比不同、镀液成分（主盐、导电盐、辅助络合剂）浓度不同及pH值不同时的阴极化曲线,讨论了镀液组分浓度及工艺参数变化对阴极极化的影响,并确定了最佳取值。研究结果表明：增大络合比、降低Cu^2＋浓度、增大硝酸钾浓度以及加入较高浓度的酒石酸钾钠均可增大阴极极化,pH值在工艺范围内对极化没有明显影响。

| Abstract: | By studying the cathodic polarization curves under different complex-ratio,bath concentration(including the concentration of main salt,conductive salt and anxiliary complexing agent) and pH in EDTA bath of cyanide-free alkaline copper plating,the influences of bath composition on the cathodic polarization were discussed.The results indicate that increasing complex-ratio,lowering the concentration of Cu2+,and using higher concentration of KNO3 and KNaC4H4O6 will make a great contribution to increase the cath... |
