Abstract. A modified simulation model of pitting corrosion is considered in potentiostatic conditions. The presence of the existence of the initial stage of the development of the pitting corrosion process of dynamic equilibrium mode is identified. It is shown that with the appearance of stable pittings on the surface the calculated frequencies of pitting nucleation and passivation decrease.
