【摘要】 铁件在由硫酸铜、硫酸亚锡、络合剂、稳定剂等组成的溶液中,可以置换镀覆不同锡质量分数的铜- 锡合金镀层,其工艺可替代氰化物预镀铜,消除氰化物污染,是实现电镀清洁生产措施之一。更多还原

【Abstract】 Cu-Sn alloy coating with different Sn content can be replacement plating out on iron and steel surface in a solution comprising of copper sulfate, stanous sulfate, complexant and stabilization agent. Such a technology can substitute for cyanide copper preplating technology to eliminate cyanid pollution. Therefore, it is one of the measures for realizing clean production in electroplating factories.更多还原
