Abstract

Abstract The corrosion inhibition properties and mechanisms of quinoline quaternary ammonium salt (QA) and L-methionine (LM) on pre-corroded Q235 carbon steel in 1wt% HCl solution were studied using the weight loss method and molecular simulation technology. The degree of pre-corrosion of steel will affect the corrosion inhibition performance of the corrosion inhibitor. QA and LM compete to adsorb to the iron surface to form a film, and the repulsion between the corrosion product and the film reduces the slow-release performance.
