Transpassive Dissolution

Abstract

The anodic dissolution behavior of nickel has not been extensively studied, but the literature on its passivation behavior is voluminous. In order to understand pitting and crevice corrosion of nickel and nickel-based alloys, it is important to obtain detailed information on the kinetics of nickel dissolution in highly acidic chloride solutions. This report presents the results of an investigation on the anodic dissolution of nickel in acidic solutions over a wide range of hydrogen ion and chloride ion concentrations with the ionic strength of both HCl-HClO4 and HCl-NaCl solutions maintained constant at either 1 or 5M.
