Sažetak
This paper presents results of the basic study on the inhibitive action of tartrate toward chloride-induced corrosion on carbon steel rebar in alkaline environment. Modification of the electrochemical behaviour and semiconductive properties of passive film formed on steel surface in the presence of tartrate were characterised by a range of electrochemical techniques in saturated calcium hydroxide. In the presence of tartrate in saturated calcium hydroxide with addition of 0.14 M sodium chloride pitting corrosion initiation was postponed for 622 mV up to potentials of oxygen evolution reaction. The hypothesis on the competitive adsorption between the chloride ions and tartrate anion through the surface complex formation was applied on the studied system.
