摘要
研究了四种新型铝合金牺牲阳极并测试了其电化学性能以及电位与时间的关系,绘制了极化曲线。实验结果表明:电流效率均高于85%,电位随时间变化不大,具有良好的活性、组织结构均匀。该材料用于海水中钢铁的阴极保护,效果良好。
Electrochemical performances of four kinds of Al-alloy sacrificial anodes were tested. The relation between potential and time was studied, and the polarization curve was drawed. The results show that all the current efficiencies are more than 85% and the potentials change little with time. The materials have good performance in the cathodic protection of iron and steel in seawater.
