| 摘 要： | 利用正交试验的配比方法炼制了不同Zn、In、Mg、Ti含量Al-Zn-In-Mg-Ti牺牲阳极9组,采用恒电流和极化曲线方法评价了牺牲阳极的电化学性能。结果表明:电流效率随着钛含量的增加呈上升趋势,随着铟含量的增加而呈下降趋势,随着锌、镁含量的增加先下降后升高。阳极为均匀溶解,未出现钝化现象,溶解过程表现出2种放电过程。最佳阳极配比(wt%)为:Zn 6.0,In 0.020,Mg 1.5,Ti 0.080,余量为Al。

| Abstract: | 9 types of Al-Zn-In-Mg-Ti sacrificial anodes with different amounts of Zn,In,Mg,and Ti were designed by the orthogonal method and casted.The electrochemical performance of Al-Zn-In-Mg-Ti sacrificial anodes was tested with constant current method and polarization curves.The results showed that the current efficiency of the anodes increased with titanium content increasing,decreased with the amount of indium increasing,and increased first,then decreased with zinc,magnesium content increasing.The anodes dissolved uniformly without passivity,and there were two different discharging processes during the dissolution.The best recipe of the anode(wt%) was Zn 6.0,In 0.020,Mg 1.5,Ti 0.080,Al Balance. |
