摘　　要：综述了电位-时间法、交流阻抗法、电化学噪声法以及多重动电位扫描技术等腐蚀电化学方法在评价涂层耐蚀性能中的应用,阐述了电化学方法评价涂层耐蚀性能的基本原理、一般规律和特点,指出电化学方法评价涂层性能具有快速、准确、方便、能提供较多定量和半定量有关涂层失效和涂层下金属腐蚀信息的优点。Application of corrosion electrochemistry methods such as EIS, ENM and MCPDP in the evaluation of the corrosion protection property of organic coatings is reviewed and the general principle and characteristics of the electrochemical evaluation for coatings are described. It indicated that the electrochemical methods are fast, accurate, easy and can provide much quantitative or semi-quantitative information about coating failure and substrate corrosion.
