Abstract

Immersion tests were used to study the inhibition effects of a complex vapor phase inhibitor on rusty iron coins. Electrochemical behaviors of simulated cast iron specimens in corrosion solution with or without inhibitor have been investigated by Potentiodynamic polarization and electrochemical impedance spectroscopy (EIS) methods. The rust composition structure of the cast iron coins after corrosion inhibition treatment was analyzed by X-ray diffraction (XRD) and X-ray photoelectron spectroscopy (XPS). Scanning Electron Microscope (SEM) has been used to detect the morphology change before and after inhibition treatment. The results show that the vapor phase inhibitor has a good synergistic inhibition effect. The corrosion potentials of cast iron electrode were positive shift and passivation phenomenon has been tested. A steady deposit film containing Fe2O3 and α-FeOOH were formed on the surface of the specimen. A chemisorption was formed between the inhibitor and iron coin surface rust, and the rust changed compact. It increases the corrosion resistance of the rust layer.
