摘要
介绍了一种在钢铁基体上碱性无氰光泽镀铜的工艺。该工艺不使用剧毒的氰化物,而用优选合成的配位剂(AZO-b)取代。研究了pH值和电流密度对镀层性能的影响。结果表明:镀层与钢铁基体之间的结合力好,镀液使用8个月后仍保持稳定,镀层呈半光亮的金红色。
A process of alkaline cyanide-free bright copper plating on steel substrate is presented. The process uses an optimized synthetic complexing agent （AZO-b） instead of toxic cyanide. The effects of pH value and current density on coating properties were investigated. The results show that the binding force between coating and steel substrate is good, and the bath is still stable after 8 months of operation, with a semi-bright golden red coating.
