中文摘要：

在氯化物一硫酸盐混合体系中，在铁基上进行滚镀Fe-Ni-Cr合金实验，结果表明：滚镀所得的Fe-Ni-Cr合金镀层铬的含量只有2％左右，难以提高，且镀层表面质量不佳，常出现滚桶眼子印现象。通过对影响滚镀Fe-Ni-Cr合金镀层质量和镀层成分的因素进行分析，认为局部电流密度过大是影响滚镀Fe-Ni-Cr合金镀层质量的主要因素；铬盐浓度、pH值、温度以及Cu^2＋、Fe^3＋杂质离子是影响镀层成分的主要因素。并对Fe-Ni-Cr合金的应用前景和目前存在的问题进行了阐述。

英文摘要：

Fe-Ni-Cr alloy electrodepositing experiment on iron substrate in chlorid-sulfate solution by barrel plating was performed. The Fe-Ni-Cr alloy quality was bad and the content of Cr was only about 2% by barrel plating. The phenomenon of barrel roll eye stamp often appeared. Factors affecting the quality and composition of barrel plated Fe-Ni-Cr alloy were analyzed. The factor affecting the quality of barrel-plated Fe-Ni-Cr alloy was that the local cathodic current density was too powerful. The main factors affecting the composition of barrel-plated Fe-Ni-Cr alloy were the concentration of chromium salt in the bath, pH, temperature and impurity ions of Cu^2＋ and Fe^3＋. The problems of Fe-Ni-Cr alloy plating at present and its application prospect are presented.
