Anticorrosion requirements for the metallurgy, automotive, and aeronautical industries have increased in recent years, for which alternative plating chemicals must be developed. This study focuses on obtaining a Zn-Ni alloy plating with higher corrosion resistance and brightness. For this purpose, tetraethylenepentaamine as complexing agent, triethanolamine as the surfactant, and gelatin and [Formula: see text]-aminobenzenesulfonic acid as brightening agents for the plating were selected and their optimal concentrations were determined for applications. The optimal Zn-Ni ratio and plating thickness were analyzed using an X-ray Dal device. Improved plating performance of the Zn-Ni alloys was achieved with a Zn-Ni alloy containing 12–14% Ni.

三乙醇胺、对氨基苯磺酸和明胶对锌镍合金镀层性能的研究

近年来，冶金、汽车和航空工业的防腐要求有所提高，因此必须开发替代电镀化学品。本研究的重点是获得具有更高耐腐蚀性和亮度的锌镍合金镀层。为此，选择了四亚乙基五胺作为络合剂，三乙醇胺作为表面活性剂，明胶和[分子式：见正文]-氨基苯磺酸作为电镀的光亮剂，并确定了它们的最佳应用浓度。使用 X 射线 Dal 装置分析最佳 Zn-Ni 比率和镀层厚度。使用含有 12-14% Ni 的 Zn-Ni 合金可以改善 Zn-Ni 合金的电镀性能。
