    Abstract

    A magnesium alloy oxidation in alkaline solutions was investigated by electrochemical impedance spectroscopy. Recorded impedance spectra exhibited up to two capacitive loops, suggesting oxidation trough adsorbed intermediates. For a kinetic description of reaction mechanism, equation of the parameters of Voight-type electrical equivalent model were obtained and used for magnesium alloy oxidation in open circuit conditions.
