Title
(EN) COMPOSITE MATERIAL AND PREPARING METHOD OF THE SAME
(FR) MATÉRIAU COMPOSITE ET SON PROCÉDÉ DE PRÉPARATION
Abstract
(EN) The present invention discloses a composite material comprising: a substrate with an anodic oxide film layer having micropores; and at least one kind of dye filled in the micropores, wherein amount of the same kind of dye is gradient distribution on at least part of the substrate. The composite material has an even, metal gloss, uneasily scratched and wore out surface with gradually changed color. Moreover, the present invention also provided a method of preparing the same.
(FR) L’invention concerne un matériau composite comprenant : un substrat revêtu d’une couche de film d’oxyde anodique doté de micropores; et au moins un type de colorant qui remplit les pores, la quantité de colorant présentant une distribution de gradient sur au moins une partie du substrat. Le matériau composite présente une surface régulière usée à brillance métallique, qui ne se raye pas facilement dont la couleur change progressivement. L’invention concerne également un procédé de production du matériau composite.
