Abstract (en)

[origin: WO2009135635A1] The invention relates to a method for compressing a component made 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 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.
