A process for forming an improved anodizing film on the surface of an aluminum alloy material. The film is impregnated with an amorphous substance which fills pores formed in the film during its growth. If the film has a flaw reaching the aluminum alloy material, the amorphous substance and aluminum form a layer of passivity which restrains the corrosion of the aluminum alloy material.
Procédé pour former un film d'anodisation améliorée sur la surface d'un matériau d'alliage d'aluminium. Le film est imprégné d'une substance amorphe qui remplit les pores formés dans le film pendant sa croissance. Si le film présente un défaut qui atteint le matériau d'alliage d'aluminium, la substance amorphe et l'aluminium forment une couche de passivité qui limite la corrosion du matériau d'alliage d'aluminium.
