摘要
采用电化学方法和阳极消耗率评价法研究了高硅铸铁阳极在方波脉冲电流作用下的电化学性能。结果表明，方波脉冲电流作用下，阳极表面状态的变化与直流作用时基本相同，钝化膜未被破坏。同等条件下阳极的消耗率比直流作用时的小。因此，在所研究的介质中高硅铸铁阳极可以用于方波脉冲电流阴极保护。
The electrochemical performance of High Silicon-Iron Anodes Exerted by Square Wave Pulsed Currents (SWPCs) was studied by electrochemical. The results showed that the change of surface state of the HSI anode polarized by anodic SWPCs was approximately as same as that polarized by the direct current (DC), and the passive film on the anode had not beau destroyed. Under the same condition, the con- sumption rate of the anode exerted by SWPCs was smaller than that exerted by DC. So in the solution studied the HSI anode could be used in pulsed current cathodic protction system.
