設計された応力プロファイルを有するコーティングされたガラス系物品
Document Type and Number:
Japanese Patent JP7142648
Kind Code:
B2
Abstract:
A glass-based substrate having a Young's modulus, a first surface, and a second surface. A coating, on at least one of the first and second surfaces, having a Young's modulus equal to or greater than the substrate Young's modulus. A compressive region having a compressive stress CS of from 750 MPa to 1200 MPa at a surface and extending to a depth of compression (DOC). The compressive region having a first portion and a second portion, the first portion extending from the first surface up to a first depth, the second portion extending from the first depth to the DOC, points in the first portion comprise a tangent having a slope that is less than −15 MPa/micrometers and greater than −60 MPa/micrometers, and points in the second portion comprise a tangent having a slope that is less than or equal to −1 MPa/micrometers and greater than −12 MPa/micrometers.
