THEORY OF THE POLARIZATION CURVE TECHNIQUE FOR STUDYING CORROSION AND ELECTROCHEMICAL PROTECTION

Abstract

This study of the analysis of polarization curves is based on the identification of the partial currents of the single electrochemical reactions involved. The relationship between the gradient of polarization curves and the corrosion rate in uninhibited corrosion processes is investigated. The analysis of polarization curves is explained and two methods of using polarization curves in corrosion studies are compared. The conditions for stability of the active and the passive states are specified for application in anodic and cathodic protection.
