The role of chromium in corrosion-electrochemical behavior of carbon steels
In neutral (рН 7,55) and alkalescent (pH= 8,74) chloride-containing solutions there was examined the electrochemical corrosion behavior of carbon steel model containing up to 1,05 % Cr. It is shown that the chromium containing in carbon steel hampers their passivation, but microalloying it with titanium has a beneficial effect on their passivity and pitting resistance. The view is suggested that the observed effect of chromium and titanium on passivity and pitting resistance of low-alloy steels is connected with the change of the energy state of the surface of the metal.
