应用多重动电位扫描极化技术测评有机涂层／金属体系的耐腐蚀性林昌健（固体表面物理化学国家重点实验室，厦门大学厦门３６１００５）Ｔ．Ｎｇｕｙｅｎ（美国国家标准与技术研究院）１引言有机聚合物涂层／金属体系的腐蚀已成为腐蚀界的一个研究热点［‘－‘］．影响有机涂层下金属腐蚀破坏的因素十分复杂，可归结为（ｌ）基底金属的性质，（２）金属／有机涂层界面特征和（３）有机聚合物涂层的性质·此外，外界环境也是影响?...

Multicyclic potentiodynamic polarization(MCPDP) technique was used to rapidly evaluate the corrooion resistance of organic coat/mrtsl system.Some faCtors affecting corrosion resistance of the coated steel,such as the type Of organic coatings,film thickness,defects in the coating,chemical state at interfaCe between metal and organic coating,and cO8ting curing condition,were examined.The explicable data Of MCPDP measurements were obtained and discussed.It was further indicated that the MCPDP technique as an electrochemical method for assessing anti-corrosion performance of organic coatings may have a number of adVantages:being fast,being reliable and sensive,and simplicity in both operation and interpretation of the experimental results.
