综述了大气腐蚀的电化学研究方法,尤其是薄液膜下 的电化学交流阻抗(EIS)和Kelvin探针技术的应用,比较了不同方法的优缺点.EIS比较适合 于研究薄液膜下金属的腐蚀历程;Kelvin探头适合于研究金属表面的局部腐蚀.最后展望了 大气腐蚀的研究趋势.
In this article,the electrochemical methods for atmo spheric corrosion research were summarized,especially in the application of EIS and Kelvin probe technique for corrosion of metals under thin electrolyte film. Among these m ethods,EIS is more effective for studying the corrosion mechanism of metal under thin electrolyte film;Kelvin probe is also suitable for investigating localized corrosion on the surface of metal.In the end,a prospects of atmospheric corrosi on research in the future is also described.
