摘要
在天然海水中研究了合金元素镓、锡、铋等对Al-Zn-In系牺牲阳极电化学性能的影响,同时研究对比了各牺牲阳极的溶解形态、电流效率等。结果表明,镓含量为0.22%(质量分数,下同),锡为0.05%及铋为0.02%时,AlZn-In-Ga-Sn-Bi活性牺牲阳极的各项性能均达到最佳。
The effects of alloying elements （Ga, Sn and Bi） on electrochemical performance of Al-Zn-In aluminum alloy sacrificial anode were studied in natural seawater. The dissolution forms, current efficiencies and other characteristics of sacrificial anodes also studied. The results show that the optimum contents of alloying elements are.. 0.22% Ga, 0. 05% Sn and 0. 02% Bi.
