Electrochemical Modification of the Steel Surface for the Corrosion Protection in Aqueous Media. Influence of the Products of Dissolution of Electronegative Metals

摘要

By the method of polarization resistance, we obtain the dynamic characteristics of corrosion processes accompanied by the formation of protective layers on 20 steel in water with low, medium, and high levels of hardness and salinity with the use of the anodic dissolution of Al, Zn, and Mg as a method of corrosion protection. It is shown that the cathodic polarization of the corroded surface from a protector or a source of direct current affects the morphology of the obtained films and significantly increases the degree of protection.
