摘要
以纯铜为研究对象,采用开路电位、动电位极化曲线和交流阻抗谱(EIS)等电化学方法和扫描电镜(SEM/EDS)技术研究了铜在模拟海水中的腐蚀电化学行为和机理。本实验涉及电解质溶液、原电池和电解池的相关知识,同时还涉及表面形貌及成分分析等相关知识,并将这些知识应用于金属腐蚀研究中,综合性较强,可作为大学本科生二年级或研究生一年级的综合实验教学内容。
The corrosion behavior and mechanism of copper in simulated seawater were studied by the electrochemical methods, such as open potential, potentiodynamic polarization, electrochemical impedance spectroscopy(EIS), and scanning electron microscopy(SEM/EDS). This experiment involves the related knowledge of electrolyte solution, primary battery and electrolytic cell, and also related knowledge of surface morphology and composition analysis, which are applied to the research of metal corrosion and can also be used as a comprehensive experimental teaching content for undergraduate students of grade two or graduate students of grade one.
