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.

The electrochemical modification of benzidine on the surface of industrial pure iron was studied. The conditions of the modification were explored. The corrosion resistance of the modified film in different media was studied by a variety of electrochemical methods. The surface modification of benzidine The composition and structure of the membrane were studied.The results show that the benzidine modified film has good protective effect on industrial pure iron and has good corrosion resistance in weak acid, sodium chloride and strong alkaline medium.According to the experiment As a result, the corrosion inhibition mechanism of the modified film was discussed in this paper.
