Patent number: 10358386Abstract: Methods of forming a sheet glass product comprising a plurality of growth-limited glass bump spacers. According to the methods, a glass pane of the sheet glass product is irradiated with laser radiation to locally heat the glass pane at a plurality of spacer localities and induce growth of a plurality of glass bump spacers in the glass pane. The growth of the plurality of glass bump spacers is limited by utilizing a growth-limiting plate comprising a scattering surface portion. The scattering surface portion of the growth-limiting plate mitigates damage to the growth-limiting plate and may also mitigate damage to the glass pane. Vacuum insulated glass products and systems for forming a growth-limited sheet glass product are also provided.Type: GrantFiled: April 12, 2016Date of Patent: July 23, 2019Assignee: Corning IncorporatedInventors: Richard Robert Grzybowski, Daniel Ralph Harvey, Alexander Mikhailovich Streltsov

Patent number: 9656910Abstract: Methods of forming a glass article are disclosed. In one embodiment, a method of forming a glass article includes translating a pulsed laser beam on a glass substrate sheet to form a laser damage region between a first surface and a second surface of the glass substrate sheet. The method further includes applying an etchant solution to the glass substrate sheet to remove a portion of the glass substrate sheet about the laser damage region. The method may further include strengthening the glass substrate sheet by an ion-exchange strengthening process, and coating the glass substrate sheet with an acid-resistant coating. Also disclosed are methods where the laser damage region has an initial geometry that changes to a desired geometry following the reforming of the glass substrate sheet such that the initial geometry of the laser damage region compensates for the bending of the glass substrate sheet.Type: GrantFiled: February 5, 2016Date of Patent: May 23, 2017Assignee: CORNING INCORPORATEDInventors: Brandon Allen Bazemore, Jeffrey Alan Decker, Jiangwei Feng, Diane Kimberlie Guilfoyle, Daniel Ralph Harvey, Yuhui Jin, Laurent Joubaud, Xavier Gerard Lafosse, Alexander Mikhailovich Streltsov, Ljerka Ukrainczyk

Patent number: 9321680Abstract: A method for fabricating a high-density array of holes in glass comprises providing a glass sheet having a front surface and irradiating the glass sheet with a laser beam so as to produce open holes extending into the glass sheet from the front surface of the glass sheet. The beam creates thermally induced residual stress within the glass around the holes, and after irradiating, the glass sheet is annealed to eliminate or reduce thermal stress caused by the step of irradiating. The glass sheet is then etched to produce the final hole size. Preferably, the glass sheet is also annealed before the step of irradiating, at sufficiently high temperature for a sufficient time to render the glass sheet dimensionally stable during the step of annealing after irradiating.Type: GrantFiled: May 30, 2012Date of Patent: April 26, 2016Assignee: CORNING INCORPORATEDInventors: Ta-Ko Chuang, Daniel Ralph Harvey, Alexander Mikhailovich Streltsov

Patent number: 8955358Abstract: Vacuum-insulated glass (VIG) windows (10) that employ glass-bump spacers (50) and two or more glass panes (20) are disclosed. The glass-bump spacers are formed in the surface (24) of one of the glass panes (20) and consist of the glass material from the body portion (23) of the glass pane. Thus, the glass-bump spacers are integrally formed in the glass pane, as opposed to being discrete spacer elements that need to be added and fixed to the glass pane. Methods of forming VIG windows are also disclosed. The methods include forming the glass-bump spacers by irradiating a glass pane with a focused beam (112F) from a laser (110). Heating effects in the glass cause the glass to locally expand, thereby forming a glass-bump spacer. The process is repeated at different locations in the glass pane to form an array of glass-bump spacers. A second glass pane is brought into contact with the glass-bump spacers, and the edges (28F, 28B) sealed.Type: GrantFiled: March 21, 2014Date of Patent: February 17, 2015Assignee: Corning IncorporatedInventors: Richard Robert Grzybowski, Daniel Ralph Harvey, Stephan Lvovich Logunov, Daniel Louis Gabriel Ricoult, Alexander Mikhailovich Streltsov
