Kinetics and mechanism of electrode reactions in corrosion of some metals covered with oil films in acid and neutral chloride environments

详细

Kinetics of electrode reduction reactions of dissolved molecular oxygen and hydrogen ions upon corrosion of copper and carbon steel was studied in neutral (NaCl) and weakly acidic (HCl) media. It was shown that deposition of the films comprised of trade or waste petroleum and synthetic (poly-α-olefins) oils on the studied metals does not alter the kinetic parameters of the electrode processes both in the kinetic region and in controlling mass transfer conditions. The observed regularities were explained as being results of the high porosity of the used oil films regardless of their kind.
