在铝合金牺牲阳极中添加Mg、Ti、Nb等合金元素,研究它们的含量与存在形式对牺牲阳极性能的影响,分析第二相、晶粒细化等的作用和影响。结果表明:在所讨论的含Mg铝合金牺牲阳极中,会形成一定类型的第二相,进而影响牺牲阳极的电化学性能;理想的Mg含量为2%;加入微量Ti、Nb可以有效细化晶粒,对提高牺牲阳极的电流效率有很好的促进作用,而且单独加入Ti要比同时加Ti、Nb的效果好。
The addition of Mg, Ti, Nb and other alloying elements to the sacrificial anode of aluminum alloy is carried out to study their influence on the performance of sacrificial anode and the influence of their content and existing forms on sacrificial anode performance. The results show that a certain type of second phase is formed in the sacrificial anode containing Mg alloy discussed above, which will affect the electrochemical performance of the sacrificial anode. The ideal Mg content is 2%. Adding trace amounts of Ti and Nb can effectively refine The grain size can improve the current efficiency of the sacrificial anode very well, and adding Ti alone is more effective than adding Ti and Nb at the same time.
