Abstract

L'invention concerne un procédé d'anodisation d'une pièce en alliage d'aluminium.
Conformément à l'invention, le procédé comprend les étapes successives suivantes :
  • on fournit un bain d'anodisation aqueux comportant essentiellement de l'acide sulfurique, avec une concentration comprise entre 55 g/l et 85 g/l, à l'exclusion de toute présence d'acide phosphorique ou d'acide borique ;
  • on maintient le bain précité à une température constante essentiellement comprise entre 15°C et 27°C ;
  • on plonge ladite pièce dans ledit bain ;
  • on applique à ladite pièce plongée dans ledit bain une tension essentiellement comprise entre 5 V et 30 V, avec une faible densité de courant sur ladite pièce ; et
  • on maintient ladite pièce dans ledit bain jusqu'à obtention de l'épaisseur de revêtement désirée qui est sensiblement comprise entre 1 µm et 3 µm.
