Abstract

The E/I response of a zircalloy-4 electrode in mineral acids is examined at room temperature under potentiodynamic conditions. On electrodes that have been mechanically polished and cathodically polarized, growth of the oxide phase, ZrO2, follows the formalism of the Cabrera-Mott model of high field assisted formation of thin oxide films. It is possible to propose a reaction model based on the potentiodynamic experimental parameters, in which the rate determining step is attributed to ionic transfer at the metal-oxide interface.
