Title (EN) COMPOSITIONAL MODIFICATION OF GLASS ARTICLES THROUGH LASER HEATING AND METHODS FOR MAKING THE SAME
(FR) MODIFICATION DE COMPOSITION D'ARTICLES EN VERRE PAR CHAUFFAGE LASER ET LEURS PROCÉDÉS DE FABRICATION
Abstract:
(EN) Glass articles and methods for modifying a composition of a surface portion of the glass article are disclosed. The method includes heating the surface portion of the glass article with a laser beam to a temperature within a range of about 1100?C to about 2200?C such that the heating evaporates one or more metalloids and/or one or more alkali metals present at the surface portion, and modifies the composition of the surface portion such that the surface portion has a lower alkali metals concentration and/or a lower metalloids concentration as compared to a portion of the glass article that is not heated by the laser beam.
(FR) L'invention concerne des articles en verre et des procédés pour modifier une composition d'une partie de surface de l'article en verre. Le procédé comprend le chauffage de la partie de surface de l'article en verre avec un faisceau laser à une température dans une plage d'environ 1 100 °C à environ 2 200 °C de telle sorte que le chauffage évapore un ou plusieurs métalloïdes et/ou un ou plusieurs métaux alcalins présents au niveau de la partie de surface, et modifie la composition de la partie de surface de telle sorte que la partie de surface a une concentration en métaux alcalins inférieure et/ou une concentration en métalloïdes inférieure par rapport à une partie de l'article en verre qui n'est pas chauffée par le faisceau laser.
