Résumé

The kinetic aspects of the coating formation on the 2024 aluminium alloy at different time intervals of the microarc oxidation process (MAO) in an alkaline-silicate electrolyte under the AC current are investigated. Moreover the main reasons of modifications in the MAO coating properties (corrosion resistance, microhardness) and phase composition during the process are shown. Finally, non-destructive control methods of MAO coating properties are worked out. (C) 2013 Elsevier B.V. All rights reserved.
