METHOD FOR LOCALIZED ANNEALING OF CHEMICALLY STRENGTHENED GLASS |
摘要 |
A method of providing locally annealed regions for a glass article comprising: (a) providing a strengthened glass article having a first surface compressive stress and a first depth of layer of compressive stress; (b) targeting first portions of the glass article on a first side thereof; (c) annealing the targeted first portions to a second surface compressive stress and a second depth of layer of compressive stress; and (d) repeating steps (b) and (c) to create a pattern of annealed portions of the glass article on the first side thereof. Targeted annealing can be done e.g. by focusing a laser or using microwave energy or an induction source. A method for making a laminate structure comprising a first glass layer (12), a second glass layer (16), and at least one polymer interlayer (14) intermediate the first and second glass layers. The first glass layer (12) can be comprised of a strengthened glass having a first portion with a first surface compressive stress and a first depth of layer of compressive stress and a second portion with a second surface compressive stress and a second depth of layer of compressive stress. In other embodiments, the second glass layer (16) can be comprised of a strengthened glass having a third portion with a third surface compressive stress and a third depth of layer of compressive stress and a fourth portion with a fourth surface compressive stress and a fourth depth of layer of compressive stress. |
