The influence of zinc cations on steel oxidation in nitrate solutions

The influence of zinc nitrate additives on the protective properties of the magnetite coating (MC) obtained by the oxidation of low-carbon steel in the nitrate solution at temperatures of 96–98°C has been studied by physical, electrochemical, and corrosion methods. It has been shown that, under thes...

Description
Summary:The influence of zinc nitrate additives on the protective properties of the magnetite coating (MC) obtained by the oxidation of low-carbon steel in the nitrate solution at temperatures of 96–98°C has been studied by physical, electrochemical, and corrosion methods. It has been shown that, under these conditions, iron zinc spinel ZnFeO 4 , which is introduced into an MC, can be formed. Low concentrations ( = 25–150 mg/l) of it increase the corrosion stability of steel with MC in water containing chlorides and sulfates and also at the periodic moisture condensation of the sample surface. At > 500 mg/l, MC formation stops.
