Description
Summary:This study examines the use of radical polymerization in a solution of acrylamide (AA) and oligo(oxyethylene) methacrylate (OEGMA) for corrosion and dissolution protection of steel in aerated aqueous solutions. The inhibiting efficiency of the different additives is evaluated from anodic and cathodic polarization curves as well as from polarization resistance. The corrosion protection is determined under varied medium composition and surface pretreatment conditions. The temperature effect is also studied and the thermodynamic activation parameters of the corrosion reaction are obtained. It was found that the examined compounds can afford good protection, even to an already oxidized steel surface, particularly in highly acidic solutions. At moderately elevated temperature, OEGMA provides higher inhibition efficiency compared to AA and the corrosion reaction was found to be entropy controlled.
