The invention relates to a method for compressing a device component of aluminum and/or an aluminum alloy, comprising an oxide layer on the surface that is produced in a uniform manner by anodizing. The compression method comprises a hot water compression of the component in a bath of completely desalinated water while using positive pressure for a period of at least one minute. Due to the pressure application in a closed compression chamber, the compression process is accelerated and the capacity of the anodizing unit is increased.
L'invention concerne un procédé pour compacter un composant en aluminium et/ou en alliage d'aluminium, présentant sur sa surface, une couche d'oxyde produite uniformément par anodisation. Le procédé de compactage comprend un compactage en eau chaude du composant, dans un bain d'eau totalement déminéralisée, par application d'une surpression pendant une période d'au moins une minute. Par application d'une pression dans une chambre de compactage fermée, le processus de compactage est accéléré, et la capacité de l'installation d'anodisation est accrue.
