Title (EN) COATED GLASS-BASED ARTICLES WITH ENGINEERED STRESS PROFILES
(FR) ARTICLES À BASE DE VERRE REVÊTUS AYANT DES PROFILS DE CONTRAINTE MODIFIÉS
Abstract:
(EN) 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.
(FR) L'invention concerne un substrat à base de verre ayant un module de Young, une première surface et une deuxième surface. Un revêtement, sur au moins l'une des première et deuxième surfaces, présente un module de Young supérieur ou égal au module de Young du substrat. Une région de compression présente une contrainte de compression CS de 750 MPa à 1200 MPa à une surface et s'étend jusqu'à une profondeur de compression (DOC). La région de compression comprend une première partie et une deuxième partie, la première partie s'étendant de la première surface jusqu'à une première profondeur, la deuxième partie s'étendant de la première profondeur à la DOC, des points dans la première partie comprennent une tangente ayant une pente qui est inférieure à -15 MPa/micromètre et supérieure à -60 MPa/micromètre et des points dans la deuxième partie comprennent une tangente ayant une pente qui est inférieure ou égale à -1 MPa/micromètre et supérieure à -12 MPa/micromètre.
