Result shows that the parameters of alternating electric field have marked effect on the electrochemical behavior of stainless steel, and the role of alloying element in stainless steel is different in the dissolution and deposition process.

• 结果表明：电极电化学反应总量随着交变电场频率的升高而减少，随着占空比的增加出现峰值，随着高、低电位的绝对值的增加而增加同时对交变电场下电极表面各元素的选择性溶解进行了探讨，并通过电化学测试对研究结果进行了分析。
