STABLE PITTING CORROSION OF STAINLESS STEEL AS DIFFUSION-CONTROLLED DISSOLUTION PROCESS WITH A SHARP MOVING ELECTRODE BOUNDARY

Summary. This contribution is devoted to explanation and prediction of corrosion pit propagation or stable pit growth, governed by ion transport properties in electrolytic solutions by deriving the (3D) mass balance for a body hosting a sharp dissolution front which separates the solid electrode from liquid electrolyte. The model is completed by Fick's law of diusion, governing the behavior of the dissolved metal ions.
