Mesoscopic Modeling Of Corrosion Processes: Pitting Morphology Evolution

We use cellular automata simulations at a mesoscopic scale to describe the phenomenon governing the morphology of pitting corrosion. We show that spontaneous separation of anodic and cathodic reaction zones plays a major role in determining the shape of the corroded space. The location of these zone...

Description
Summary:We use cellular automata simulations at a mesoscopic scale to describe the phenomenon governing the morphology of pitting corrosion. We show that spontaneous separation of anodic and cathodic reaction zones plays a major role in determining the shape of the corroded space. The location of these zones versus the corroded surface is a stochastic event that influences strongly the direction of the corrosion propagation.
