Model ID: 14015
This tutorial example serves as an introduction to the Corrosion Module and models the metal oxidation and oxygen reduction current densities on the surface of a galvanized nail, surrounded by a piece of wet wood, which acts as electrolyte. The protecting zinc layer on the nail is not fully covering, so that at the tip of the nail the underlaying iron surface is exposed. First the electrolyte conductivity and the electrode reaction kinetics are modeled to obtain a secondary current distribution (concentration variations in the cell are not accounted for), in a second part the oxygen transport is included to model a tertiary current distribution.
