This study investigated the effect of vapor phase corrosion inhibitors (VCI) such as imidazoline, quinoline, and urea on E36 ship steel in simulated marine atmospheric environment. The findings showed that the corrosion process was inhibited through the adsorption of these VCIs on the surface of the steel.
Purpose This study aims to investigate the effect of vapor phase corrosion inhibitor (VCI) imidazoline, quinoline and urea on E36 ship steel in simulated marine atmospheric environment. Design/methodology/approach The inhibitive effect was investigated by weight loss, potentiodynamic polarization, electrochemical impedance and Raman spectroscopy. Findings The corrosion process was inhibited by adsorption of the three VCIs on the surface of ship steel. The corrosion inhibition mechanism is the adsorption film type. The corrosion inhibitor adsorbs on the metal surface to prevent Cl- from reaching the surface of the substrate, so as to achieve the corrosion inhibition effect. Originality/value To the best of the authors' knowledge, the work described was original research that has not been published previously and not under consideration for publication elsewhere, in whole or in part.
