Zinc alloys are promising for wide uses thanks to their moderate biodegradability, good mechanical properties, and relevant biocompatibility. In this study, Zn-Zr and Zn-Zr-Mg alloys were prepared through the electro-deoxidation of ZnO-ZrO₂ and ZnO-ZrO₂-MgO mixtures in CaCl₂-NaCl molten salt at 873 K. The electrochemical reduction mechanisms of ZnO, ZrO₂, ZnO-MgO, and ZrO₂-MgO composites were studied by cyclic voltammetry using metal cavity electrodes. The electrolysis parameters, such as the molar ratio of raw oxides and electrolysis time were also investigated. The results revealed promoted the reduction of ZrO₂ and MgO through the formation of Zn and Ca-Zn alloys. Meanwhile, high melting point Zr and Zn-Zr alloys were found important in collecting more Zn and Zn-Mg alloys. A complete reduction of ZnO-ZrO₂ and ZnO-ZrO₂-MgO mixtures was achieved at ZnO contents above 2/3 of the total mass. Also, Zn, Zr, and Mg elements were homogeneously dispersed in the electrolyzed samples. In sum, the proposed method looks promising for the preparation of novel zinc-based alloys.

锌合金具有中等的生物降解性，良好的机械性能和相关的生物相容性，因此有望被广泛使用。在这项研究中，通过在873 K下将CaO ₂ -NaCl熔盐中的ZnO-ZrO ₂和ZnO-ZrO ₂ -MgO混合物电脱氧，制备Zn-Zr和Zn-Zr-Mg合金。使用金属腔电极通过循环伏安法研究了ZnO，ZrO ₂，ZnO-MgO和ZrO ₂ -MgO复合材料。还研究了电解参数，如粗氧化物的摩尔比和电解时间。结果表明促进了ZrO ₂的还原通过形成Zn和Ca-Zn合金形成MgO。同时，发现高熔点的Zr和Zn-Zr合金对于收集更多的Zn和Zn-Mg合金很重要。在高于总质量的2/3的ZnO含量下，实现了ZnO-ZrO ₂和ZnO-ZrO ₂ -MgO混合物的完全还原。此外，Zn，Zr和Mg元素均匀分散在电解样品中。总而言之，所提出的方法在制备新型锌基合金方面看起来很有希望。
