Abstract

a. Procédé d'anodisation dure d'articles en aluminium et en alliages d'aluminium. b. Procédé caractérisé en ce que l'on immerge un ou plusieurs de ces articles dans un électrolyte refroidi composé dune solution aqueuse d'un acide fort; on applique aux bornes de cet article et d'une cathode placée dans l'électrolyte, pendant une durée prédéterminée, une tension continue avec, en superposition, une tension alternative, le potentiel positif de la composante de tension continue étant, pendant au moins une partie de la durée prédéterminée, essentiellement comprise entre environ 14 et 20 volts, cette valeur étant la tension continue maximale appliquée pendant la période prédéterminée aux articles. c. L'invention s'applique à l'anodisation dure.
