This article describes the electroplating of ZnNi alloy from a modified deep eutectic solvent (DES), a mixture of choline chloride (ChCl) and ethylene glycol (EG) commonly known by its commercial name Ethaline. In this study the Ethaline was modified with propylene carbonate (PC) to decrease the solution viscosity. Boric acid was also used as an additive to improve surface finish and adhesion. The modifications were shown to increase the reduction rate of metal ions through improved mass transport and also to improve the quality of finish (morphology and interfacial adhesion) of the coating. We demonstrate that it is possible to produce dense, thick and adherent coatings of a γ-phase ZnNi alloy with 81–85% Zn on mild steel substrates using either potentiostatic deposition or controlled current pulse-plating techniques. Mild steel is a typical substrate for a sacrificial anti-corrosion coating used in many applications where the alloy serves to protect the steel from corrosion in harsh environments.

本文介绍了从改性的深共熔溶剂（DES），氯化胆碱（ChCl）和乙二醇（EG）的混合物（通常以商品名Ethaline众所周知）电镀锌镍合金的方法。在这项研究中，用碳酸亚丙酯（PC）改性了Ethaline，以降低溶液粘度。硼酸也被用作添加剂来改善表面光洁度和附着力。改性显示出通过改善的质量传递增加了金属离子的还原速率，并且还改善了涂层的光洁度（形态和界面附着力）质量。我们证明了可以生产致密，厚实和附着的γ相Zn涂层使用恒电位沉积或受控电流脉冲镀覆技术在低碳钢基材上的镍合金，含81％至85％的锌。低碳钢是牺牲防腐蚀涂层的典型基材，在许多应用中使用该合金，以保护合金在恶劣环境下不受腐蚀。
