Abstract

Distributions of current density and potential have been analyzed on a carbon steel (SS400) - stainless steel (SUS304) couple. General and galvanic corrosion results were experimentally obtained in NaCl solution for different temperatures and immersion times. The experimentally determined polarization curves defined the nonlinear boundary conditions of the Laplace's equation and numerical results have been calculated using the boundary element method. The influence of the elementary spacing and thickness as well as the effect of insulating materials in the galvanic model have been analyzed. 1 Introduction
