Abstract
Results of potentiodynamic polarization and electrochemical impedance spectroscopy (EIS) measurements for protective coatings, containing high temperature fraction of Vietnam crude oil and nitrated oil additives have been discussed. It was found that the protective composition with 10% nitrated oil additives showed highest corrosion inhibition efficiency for mild steel in 0.5M NaCl solution in the studied nitrated oil concentration range. The anodic inhibition effect remains unchanged while the cathodic inhibition effect increases with additive concentration raising. According to the EIS results, nitrated oil additives in the protective composition inhibit corrosion processes due to adsorption on the steel surface.
