Abstract

A numerical model was proposed to investigate the corrosion behavior of Cu-Zn-Fe couple in near-neutral 3.5 wt% NaCl. Evolution of current density, pH and soluble corrosion products were simulated in one-dimensional scale. The model predicted acidification on Zn surface and alkalization on Cu and Fe surfaces. pH evolution is related to corrosion products distribution. Zn 2+ is the dominant specie formed on the middle of Zn surface. Zn hydrolytes are preferentially formed above the resin. Above the cathode surfaces distant from Zn, the concentration of corrosion products remains as zero.
