Analysis of Electrical Equivalence of Corroding Iron in Sulfuric Acid Solutions

Abstract

A method evaluating the electrical equivalence of a corroding metal in a solution was proposed. The electrical responses of corroding systems to the square wave current stimuli were analyzed by the present method. The new method can not only evaluate the deviation of electrical response of the corroding system from the idealized one but also determine the necessary parameters without any arbitrariness. It was demonstrated that an idealized equivalent circuit was acceptable only for high conductive solutions in acidic media.
