摘　　要：报导从氟硼酸体系的镀液中电沉积铅镉合金的最佳配方和工艺条件.所得合金镀层结晶致密、半光亮,含镉>20%.添加剂RPC和PCT能显著提高阴极极化度.槽液中Pb/Cd的金属含量比例一定时,镀层Cd含量随电流密度的增加而增加.Optimized fluoborate bath for electrodeposition of semi-bright fine-grained lead-cadmium alloy containing >20%Cd is reported. Cathodic polarization can be significantly increased by addition of additives RPC and PCT. At a given concentration ratio of Pb to Cd in the solution, higher current density applied results in higher cadmium content in the deposits.
