通过实验室的实土埋样实验(30 d)、极化曲线、交流阻抗谱(EIS)测试和失重法对纯铜和电镀铜包钢在大港实土中的初期腐蚀行为进行了研究。在腐蚀的初期阶段，纯铜的平均腐蚀速率略低于电镀铜包钢，它的耐土壤腐蚀性能略好；纯铜和电镀铜包钢的腐蚀机制存在一定的差异，纯铜的腐蚀行为受扩散控制影响较大。

The initial corrosion behaviors of pure copper and electroplating copper-clad steel in Dagang soil were investigated by burying tests in lab for 30 d, combining polarization curves, electrochemical impedance spectroscopy ( EIS) , and weight-loss method. It is found that during the initial stage of the corrosion process, the average corrosion rate of pure copper is slightly lower than that of electroplating copper-clad steel, and pure copper exhibits a higher corrosion resistance than electroplating copper-clad steel. There are some differences in the corrosion mechanism between pure copper and electroplating copper-clad steel. The corrosion behavior of pure copper is mainly affected by diffusion control.
