[目的]针对弱酸性电镀Zn–Ni合金工艺中单阳极控制导致的镀液金属离子比例失衡问题，提出采用双电源分控双阳极策略，以提升工艺稳定性。[方法]通过独立控制锌阳极与镍阳极的电流分配比，在总电流密度2.0 A/dm2温度30℃条件下电镀Zn–Ni合金，对比了不同周期(以120 A·h为1个周期)后镀液和镀层的性能。[结果]在周期性电镀960 A·h期间，镀层的外观、厚度和Ni质量分数，以及镀液的金属盐含量、分散能力和pH基本保持恒定。[结论]使用双电源分控双阳极的方法可有效解决镀液金属离子比例失衡问题，有效提高工艺的稳定性。
Abstract：[Objective] To address the issue of imbalanced metal ion ratios in weakly acidic Zn–Ni alloy electroplating bath when using single-anode, a dual-power-supply independent dual-anode control strategy was proposed to enhance process stability. [Method] Zn–Ni alloy electroplating was conducted at total current density of 2.0 A/dm2 and temperature of 30 ℃ by independently controlling the current distribution between zinc and nickel anodes. The properties of both the bath and coatings were compared after different cycles(120 A·h per cycle). [Result] During the 960 A·h of periodic electroplating, the appearance, thickness, and Ni mass fraction of Zn–Ni alloy coating, as well as the metal salt content, throwing power, and p H of bath remained essentially stable. [Conclusion] The imbalance of metal ion ratios in bath can be effectively resolved, and the process stability is significantly improved by dual-power-supply independent dual-anode method.
