Abstract

La présente invention a pour objet une méthode efficace pour accélérer des processus d'oxydation sous micro-arc pour former une épaisse couche lisse et modifiée d'oxyde sur des produits en alliage d'aluminium. Ladite méthode fait intervenir la modification des produits en alliage d'aluminium en formant un fine couche barrière dense et non poreuse d'alumine (ou couche diélectrique) et une couche de substance de modification. Ces deux couches coexistent et ensemble servent de couches qui accélèrent le processus ultérieur d'oxydation sous miro-arc.
