Abstract

In article the results of electrochemical and gravimetrical investigations by the influence of new elaborated oligomeric salts on the base of some organic compounds on the corrosion behavior of steel samples (St.3, 45) in different mediums are presented. It was shown that protective effect of investigated oligomeric salts has been increased with increasing their molecular mass and hydrocarbon radicals. The results of research on the mechanism of protective action of oligomers and phosphorus-containing adducts are presented. Effective protection of phosphorus-containing oligomers as metal corrosion inhibitors in various aggressive environments is highlighted.
