摘　　要：介绍了在锌酸盐溶液中脉冲电镀锌-铁合金工艺。研究了镀液中氧化锌、亚铁离子和络合剂浓度、脉冲电流参数对镀层中铁含量的影响，获得了铁的质量分数为0．3%～0.6%电镀锌-铁合金工艺，并通过中性盐水浸泡实验确定了最佳耐蚀镀层的工艺条件。The zinc-iron alloy electroplating technology in zincate solution by pulse current was investigated. The factors influencing the iron content in Zn-Fe, such as the concentrations of zin- cate, ferrite sulfate and chelating agent, as well as the current parameters were discussed. The zinc-iron alloy electroplating technology, which the iron content ranges between 0. 3% and 0.6% in the alloy deposits was obtained. The optimal technology for obtaining high corrosion resistance coating was established by immersion-test.
