Influence of Imidazoline Related Corrosion Inhibitor on Corrosion of Carbon-Steels

Abstract

The corrosion inhibition performance of imidazoline derivatives, which have different dispersion quality on carbon steel was investigated with electrochemical tests and X-ray photoelectron spectroscopy in model oil and gas environments. From the potentiodynamic polarization results, used imidazoline derivatives effectively inhibited anodic and cathodic reactions. X-ray photoelectron spectroscopy analysis results suggest that used imidazoline derivatives adsorbed on the carbon steels to inhibit corrosion reaction of the steels. The possible corrosion inhibition mechanism was proposed.
