Coated glass-based articles with engineered stress profiles and methods of manufacture

Abstract:

Coated glass-based articles and methods of manufacture disclosed. An article comprises a chemically strengthened glass-based core substrate having a first surface and a second surface, a chemically strengthened glass-based first cladding substrate having a third surface directly bonded to the first surface to provide a first core-cladding interface and a chemically strengthened glass-based second cladding substrate having a fourth surface directly bonded to the second surface to provide a second core-cladding interface, wherein the core substrate is bonded to the first cladding substrate and the second cladding substrate, and there is a coating on the first cladding substrate.
