采用电化学动电位扫描和交流阻抗研究了铜在模拟斯 德哥尔摩雨水中的腐蚀行为.铜表面存在少量腐蚀产物时，铜在雨水中的腐蚀主要由电化学 机制控制；随着腐蚀产物在铜表面的大量生成和沉积，存在腐蚀产物的区域和不存在腐蚀产 物的区域，形成了电偶腐蚀电池，腐蚀产物区为阴极.
Corrosion behavior of copper in a simulated of rainw ater Stockholmarea was studied by electrochemical impedance spectrum and polariz ation curves.The corrosion process of copper in the simulated rainwater was main ly controlled by the electrochemical process at first when there was alittle cor rosion product on the surface of copper.With the formation of corrosion product, the galvanic corrosion occurred on the surface of copper between different areas without and with corrosion product.The corrosion product on the surface of copp er played a cathodic role in the galvanic cell.
