Model of a Corrosion Pit with Movement of Active Boundaries

S. Salleh, N. Stevens

Abstract


Pitting is one of the most destructive types of localized corrosion. This paper presents the mathematical model of the early stages of pitting corrosion after its initiation stage, using a commercial finite element program. In view of the chemical and electrochemical reactions inside a single pit in steel, a two dimensional model that allows the prediction of movement of boundaries of a pit is developed.
