Комбінований захист вуглецевих сталей дифузійними покриттями за участю Ti, Cr, Al та інгібиторами корозії

Abstract

The effect of diffusion coatings based on Tі, Al and Cr, Ti, Al produced by the proposed technology on the corrosion resistance of U8A steel (GOST 2283) at 20 C in a solution of sulfuric, octopic, citric, formic and lactic acid has been researched. The relationship between corrosion resistance and protective properties of coatings with the chemical, phase composition of diffusion layers and the conditions of corrosion processes has been revealed. Using electrochemical methods, the mechanism of protective effects of coatings has been researched. The possibility of increasing their protective properties by inhibitors of corrosion has been demonstrated.
