Abstract

La présente invention concerne un élément extérieur en céramique de dioxyde de zirconium et un procédé de fabrication correspondant. L'élément extérieur comprend un substrat en céramique de dioxyde de zirconium, un film anti-empreintes digitales, et une couche intermédiaire prévue entre le substrat en céramique de dioxyde de zirconium et le film anti-empreintes digitales et la liaison respectivement au substrat en céramique de dioxyde de zirconium et au film anti-empreintes digitales, le matériau de la couche intermédiaire étant du dioxyde de zirconium et du dioxyde de silicium. Due à la présence de la couche intermédiaire, une force adhésive entre le substrat de dioxyde de zirconium et le film anti-empreintes digitales est accrue, ce qui améliore ainsi la résistance à l'abrasion du film anti-empreintes digitales de l'élément extérieur.
