Abstract

L'invention porte sur un procédé de coloration électrolytique d'un matériau en aluminium, procédé consistant à immerger ce matériau comprenant de l'aluminium ou un alliage d'aluminium, former un film anodisé dans un bain de traitement de coloration électrolytique contenant un sel métallique soluble et faire passer une forme d'onde de courant continu à l'aide du matériau en aluminium sous forme d'anode, puis soumettre ce matériau en aluminium à un prétraitement avant l'étape de coloration, et ensuite à un traitement de coloration électrolytique à courant alternatif dans le même bain de traitement. L'amélioration apportée à ce procédé consiste à effectuer le prétraitement précité avant la coloration jusqu'à ce que la tension et le courant atteignent des valeurs prédéterminées respectives. Le procédé amélioré peut être utilisé pour réduire considérablement les irrégularités de coloration non seulement dans un lot d'excitation, mais également entre différents lots d'excitation, et cela pour produire un matériau en aluminium de coloration uniforme, stable et facile à produire à l'échelle industrielle.
