| 中文摘要: |
| 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Cu2+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。 |
| 英文摘要: |
| 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 cyanidefree 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 KNO3and KNaC4H4O6will make a great contribution to increase the cathodic polarization, pH has no significant effect on the polarization. |
