Abstract

The mechanism of magnesium anodizing after mechanical polishing or HF pickling was studied. X-rayPhotoelectron Spectroscopy and Photocurrent Spectroscopy were employed to characterize both theinitial films formed on Mg soon after surface treatments and the anodic films grown in strongly alkalinesolutions. Electrochemical and capacitance measurements were performed in order to study the oxidationprocess and to check if the kinetic of growth fits the Mott–Cabrera high field model. From Tafel plots it waspossible to estimate the activation distance, while the simulation of the barrier layer growth as a functionof the potential at high scan rate allowed to estimate the other kinetic parameters of Mott–Cabrera model.An influence of the initial layer composition on such parameters was evidenced.
