摘要: 本文提出了用电场理论和电化学理论相结合的方法来研究交流腐蚀这一途径。在变化极快,强度甚大的交流干扰电场作用下。金属的电化学腐蚀过程发生变化。此时,电场强度是一个重要的物理量。测量和分析了干扰电压、电位梯度、点电流密度、失重量及腐蚀坑深后,可以看出失重量随平均电流密度而增加,腐蚀坑深随干扰电压而加剧。根据埋片实验结果,初步提出了交流腐蚀临界安全电压指标。

Abstract：In this paper, we propose a method to investigate the AC corrosion on the basis of the effect of electric field combination with that of electrochemistry. Under the effect of strong yet swiftly changing electric field, the electrochemical process of corrosion has changed essentially, and the intensity of electric field is an important physical parameter. After measurement and analysis of the interfering voltage, potential gradient, the point current density, the weight-loss increases with average current density, and the depth of penetration increases with the interfering voltage. Based on experimental results the authors have proposed safety limits of voltage on prevention of corrosion.
