Title
(EN) GLASS-CERAMIC ARTICLE WITH SURFACE PASSIVATION LAYER AND METHODS FOR PRODUCING THE SAME
(FR) ARTICLES EN VITROCÉRAMIQUE À COUCHE DE PASSIVATION DE SURFACE ET LEURS PROCÉDÉS DE PRODUCTION
Abstract
(EN) A glass-ceramic article is provided that includes a surface passivation layer. The passivation layer is an oxide layer and has a thickness of greater than or equal to 20 nm to less than or equal to 200 nm and a RMS surface roughness of less than or equal to 3 nm. The surface passivation layer may be formed with a liquid phase deposition process. The glass-ceramic article may include an easy to clean layer disposed on the surface passivation layer, and the glass-ceramic article may be chemically strengthened. The glass-ceramic article may be used in a consumer electronic product.
(FR) L'invention concerne un article en vitrocéramique qui comprend une couche de passivation de surface. La couche de passivation est une couche d'oxyde et a une épaisseur supérieure ou égale à 20 nm et inférieure ou égale à 200 nm et une rugosité de surface RMS inférieure ou égale à 3 nm. La couche de passivation de surface peut être formée par un processus de dépôt en phase liquide. L'article en vitrocéramique peut comprendre une couche facile à nettoyer disposée sur la couche de passivation de surface et l'article en vitrocéramique peut être renforcé chimiquement. L'article en vitrocéramique peut être utilisé dans un produit électronique grand public.
