Abstract Electrochemical modification of surface films on metals is an effective means for anti-corrosion brought forward recently. The modification of aniline and its derivatives on iron-based alloy was investigated in this work. The anti-corrosion performance of modified films was studied in various solutions under different modification conditions by using some electrochemical techniques, such as polarization resistance method, polarization carve and impedance measurements. The surface morphology, composition and structure of modified films were analysed by modern physical analysis techniques, such as AES, XPS, SEM, etc. The results show that the modified films of aniline and its derivatives on iron-based metal surface have good anti-corrosion performance,and pitting resistance and passivity of modified films on 18-8SS are greatly improved. The protection mechanism of modified films and the effect of both structure of modification substances and substitute group position on corrosion resistance were discussed.
