Kinetics of Corrosion of passive metals - part I: Concepts and Theory

Abstract

A new electrochemical method was developed to overcome the problems met with in linear polarization and other small amplitude potential perturbation techniques for the evaluation of corrosion rates of passive metals. The method is based on an anal. of a galvanostatic polarization transient in the Tafel region and its decay on open circuit. Linear and Tafel polarization results for passive metals with conducting or insulating films were analyzed from a theorem viewpoint
