Abstract
(EN)
Provided are a precious metal article having a plated layer at its surface and a preparation method therefor. The precious metal article comprises: a precious metal matrix and a physical vapor deposition layer or a water plated layer or an electrophoretic layer and a transparent film layer sequentially attached to the precious metal matrix, the precious metal being gold or silver. The film layer formed on the surface of the precious metal article is thinner, and can exhibit different colors and improve the single color of the precious metal matrix, and the change in color does not affect the color of the precious metal matrix. Furthermore, the transparent film layer can stabilize the formed film layer, has strong abrasion resistance, and can make the formed color last without fading.

L'invention concerne un article en métal précieux présentant une couche plaquée sur sa surface et son procédé de préparation. L'article en métal précieux comprend : une matrice en métal précieux et une couche de dépôt physique en phase vapeur ou une couche plaquée d'eau ou une couche électrophorétique et une couche de film transparente fixées séquentiellement à la matrice en métal précieux, le métal précieux étant de l'or ou de l'argent. La couche de film formée sur la surface de l'article en métal précieux est plus mince, et peut afficher différentes couleurs et améliorer la couleur unique de la matrice en métal précieux, et le changement de couleur n'affecte pas la couleur de la matrice en métal précieux. En outre, la couche de film transparente peut stabiliser la couche de film formée, présente une forte résistance à l'abrasion et peut permettre la préservation de la couleur formée sans décoloration.
