GLASS-CERAMIC ARTICLE WITH SURFACE PASSIVATION LAYER AND METHODS FOR PRODUCING THE SAME

Abstract:

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.
