摘要/Abstract

摘要： 研究了联苯胺在工业纯铁表面的电化学修饰,对修饰工艺条件进行了探索,并采用多种电化学方法研究了修饰膜在不同介质中的耐蚀性能,用现代物理表面分析技术对修饰膜的组成和结构进行了研究.研究结果表明,联苯胺修饰膜对工业纯铁有很好的保护作用,在弱酸性、氯化钠以及强碱性介质中有良好的阻蚀性能.根据实验结果,本文对修饰膜的缓蚀机理进行了探讨.

Abstract: The modification ot benzidine on the surface of industrial pure iron was investigated with regard to its technology and method. The anti-corrosion performance of modified film in various solutions was discussed by using some electrochemical techniques. The surface composition and structure of modified film were analysed by Auger electron spectroscopy, Fourier transform-infrared spectroscopy and X-ray diffraction. The research results showed that the modified film had good anti-corrosion performance in weak acid, neutral solution containing Cl- and strong alkali. The protection mechanism of modified film was also discussed.
