介绍了一种硫酸盐电镀锌铁合金工艺及新型光亮剂。 研究了镀液中 FeSO₄ ·7 H₂O 浓度、锌铁总离子浓度、光亮剂用量、阴极电流密度、pH 值、温度等因素对镀层含铁量的影响。 结果表明:随着镀液中锌铁总离子浓度和温度的升高,镀层的含铁量降低;随着阴极电流密度和 pH 值的增大,镀层的含铁量先增加,后降低;随着 FeSO₄ ·7 H₂O 浓度的升高,镀层的含铁量增加。 探讨了新型光亮剂对镀层的影响,获得了最佳电镀方案。

A sulfate Zn-Fe alloy electroplating process and new brightener was described, and the influences of ion concentration of plating, mass concentration of FeSO₄ ·7 H₂O, dosage of brightener, cathode current density, pH, temperature on the surface of coating and iron content were discussed. The results showed that the mass fraction of iron in the coating decreases as the ion concentration of zinc and iron as well as temperature increased. As the incrase of cathode current density as well as pH it increase first , when reaching a value the mass fraction Fe in the coating increases with their mass fraction decreases.It incrases as the increase of the concentration of FeSO₄ ·7 H₂O. The article found out the optimum plating and explored the influence of new brightener on the coating.
