摘　　要：考察PEG1000、PEG20000、十八烷基二甲基苄基氯化铵(OC)以及超支化Gemini季铵盐作为添加剂使用时对锌镁合金电镀液极化能力的影响。取4种添加剂各自对于电镀液极化能力影响的最优量,进行复配实验考察。最终发现复配方案为PEG20000 3g/L、十八烷基二甲基苄基氯化铵2g/L时,制备的合金镀层中镁的含量最高,同时相对于纯锌镀层,耐腐蚀性能大为改善。The influence of PEG1000, PEG20000, 0（2 and Gemini as additives on the polarizing capability of the Zn-Mg plating solution was researched. Optimal content of each additive in the plating solution was used to observe the polarizing capability of the Zn-Mg plating solution. Finally, it is confirmed that the formulation with PEG20000 3 g/L and OC 2 g/L as additives, could prepare the plated coating with a high volume of Mg, in contrast to electrogalvanizing, which demonstrated higher corrsion resistances.
