Description	It is well known that the presence and concentration of chloride as well as temperature play key role in determining whether localized corrosion of carbon steel occurs. The effect of chloride concentration on Epit of carbon steel for water extracts of anticorrosive pigments has not yet been however examined. It can be due to the fact that sufficient concentration of chloride for pitting of carbon steel can be low in this type of environments. In addition to it water extracts of anticorrosive pigments are environment where carbon steels typically do not undergo deep penetration by pitting corrosion and exhibit rather weak protective passive films. All these facts make necessary to test applicability of Epit approach for carbon steel and the conditions under which passivity and localized corrosion are possible in this type of environment. This work describes cyclic voltametry method for the rapid screening of inhibition efficiency of some anticorrosive pigments for pitting corrosion of carbon steel. The chosen method is able to determine Epit value of carbon steel for given type of tested extract during the first scan as well as possible pitting initiating within occluded regions during the reverse scan. Possible loss of pH control within occluded regions, such as matrix-inclusion interfaces, is discussed.
