Abstract

The protective effect of an organic compound of imidazole class on the corrosion of mild steel in sulfuric acid was studied. Modification of the organic base with bromine anions increases the protection effect. The blocking-activation mechanism of the protective effect of benzimidazole hydrobromide was determined by gravimetry, impedancesometry and polarization measurements. The interaction of adsorbed particles in the adsorption layer was found to be increased with increasing organic salt concentration. The features of the cellular microstructure of the films have been studied by scanning electron microscopy. AFM imaging study showed that the Fe coatings have a globular character and depend on the type of inhibitor and its concentration. It has been established that the most reliably protect Fe from corrosion are the coatings representing aggregates of large, accreted globules with maximum electrical conductivity.
