摘要:
Asymmetrically strengthened glass articles, methods for producing the same, and use of the articles in portable electronic device is disclosed. Using a budgeted amount of compressive stress and tensile stress, asymmetric chemical strengthening is optimized for the utility of a glass article. In some aspects, the strengthened glass article can be designed for reduced damage, or damage propagation, when dropped.
摘要:
A method includes forming a glassy article. The glassy article includes a first glassy layer and a second glassy layer adjacent to the first glassy layer. The second glassy layer includes a photosensitive glass. The glassy article is exposed to radiation to form an exposed glassy article. The exposed glassy article is subjected to a heat treatment, whereby a plurality of inclusions is formed in the photosensitive glass of the second glassy layer.
摘要:
A method for welding together glass workpieces where one of the workpieces has metal nanoparticles positioned at or near the surface to be welded. The method comprises positioning the workpieces in operative contact at an interface where a weld is to be formed, applying a laser beam to be incident upon the interface wherein energy from the laser beam is absorbed by the nanoparticle bearing workpiece and the energy from the laser beam is transferred to the glass surrounding the metal nanoparticles to heat the glass and to weld the workpieces together.

Heavy-metal-free glass enamels are applied to glass and fired. After firing, the coated glass can subsequently be ion exchanged to give a chemically strengthened, decorated glass article.

The invention relates to a method for structuring a surface, in other words, for forming at least one set of irregularities or patterns (2) having a submicronic height H and at least one characteristic lateral dimension W referred to as the micronic or submicronic width, on a surface of a material (1), in particular a glass, by means of ion-beam etching using an optionally neutralised ion beam, characterised in that said method comprises the following steps: providing said material with a thickness of at least 100 nm, the material being hybrid and solid and including a single or mixed oxide of element(s), the molar percentage of oxide in the material being at least 40%, in particular 40% to 94%, and at least one species, separate from the oxide element(s), in particular a metal, the molar percentage of species in the material ranging from 6% to 50% and being lower than the percentage of said oxide, with at least the majority of the species having a largest characteristic dimension smaller than 50 nm, said hybrid material in particular being metastable prior to said etching; optionally heating said hybrid material prior to said etching; and structuring the surface of said hybrid material with an etching time of less than one hour on an etching surface of more than 1 cm 2 until said set of patterns is formed, the structuring step optionally including heating the hybrid material.

This invention relates to a method of making glass. In certain example embodiments, a major surface(s) of the glass is treated with aluminum chloride (e.g., AlCl3) at or just prior to the annealing lehr. The aluminum chloride treatment at or just prior to the annealing lehr, in either a float or patterned line glass making process, is advantageous in that it allows the treatment to be performed at a desirable glass temperature and permits exhaust functions in or proximate the annealing lehr to remove byproducts of the treatment in an efficient manner. In certain example embodiments, the glass may be polished for thinning after the treatment, with the polishing being performed on a major surface of the glass opposite to a major surface which has been treated with aluminum chloride.
摘要:
The invention relates to a method for doping and/or coloring glass. In the method a two- or three-dimensional layer is formed on the surface of the glass, and the layer is further allowed to diffuse and/or dissolve into the glass to change the transmission, absorption, reflection and/or scattering of the electromagnetic radiation of the glass. The layer of nanomaterial comprises at least one component that causes the above-mentioned change and at least one component that lowers the melting point of the above-mentioned component causing the change.
