利用失重测量、扫描电子显微镜、x射线衍射、动电位极化和微距电极原位电化学阻抗谱（EIS）研究了铜暴露在模拟沿海工业大气中的腐蚀行为。结果表明，腐蚀动力学遵循经验方程D = At-n。主要腐蚀产物为Cu2O、Cu2Cl(OH)(3)和Cu4Cl2(OH)(6)。腐蚀过程中形成的腐蚀产物是由松散的外层和致密的内层组成的两层结构。SO2已被发现促进Cu4Cl2（OH）的形成(6)。(C) 2016年由爱思唯尔有限公司代表《材料科学与技术杂志》编辑部出版。
The corrosion behavior of copper exposed in a simulated coastal-industrial atmosphere has been investigated using weight loss measurement, scanning electron microscopy, X-ray diffraction, potentiodynamic polarization and in-situ electrochemical impedance spectroscopy (EIS) with micro-distance electrodes. The results show that corrosion kinetics follows the empirical equation D = At-n. The main corrosion products are composed of Cu2O, Cu2Cl(OH)(3) and Cu4Cl2(OH)(6). A two-layer structure comprising a loose outer layer and a compact inner layer forms the corrosion products during corrosion process. SO2 has been found to promote the formation of Cu4Cl2(OH)(6).
