Atmospheric Corrosion

Model ID: 16065


This model simulates atmospheric galvanic corrosion of an aluminum alloy in contact with steel. The electrolyte film thickness depends on the relative humidity of the surrounding air and the salt load density of NaCl crystals on the metal surface. Empirical expressions for the oxygen diffusivity and solubility are also included in the model in order to derive an expression for the limiting oxygen reduction current density.
