A model for surface charge-assisted barrier film growth on metals in acidic solutions based on ac impedance measurements

A kinetic model of the passivation of metals via formation of a dual layer comprising a barrier film and a salt overlayer is proposed. It is assumed that the barrier film grows through high field-assisted migration of defects. Ionic surface charges are formed both at the metal/barrier film and barri...
