摘要
在含有 TZ 微量元素和 TCX 混合浆液的焦磷酸盐溶液中制备的 Sn-Co 合金复合镀层,不仅外观光亮、优美,而且酷似铬镀层。这种复合镀层具有较高的硬度和抗蚀性。该工艺合理,操作方便,而且镀液稳定性好。另外,它还具有较好的分散能力、较高的电流效率和污染小等优点。该技术既能用于挂镀,又能用于滚镀,特别适用于一些较小零件的滚镀工艺。
A Sn-Co alloy composite coating,obtained from a pyrophosphate bath containing TZ microtrace elements and TCX mixture,looks bright,beautiful and like chromium.The composite coating has a higher hardnes and corrosion resistance.It is reasonable in process,easy in operation and good in stability.It has features of better throwing power,higher current efficiency and less pollution.The technology can be used in both rack and barrel platings,esp.in barrel plating of smaller parts.
