20130224492 | ION EXCHANGED GLASSES VIA NON-ERROR FUNCTION COMPRESSIVE STRESS PROFILES - Glasses with compressive stress profiles that allow higher surface compression and deeper depth of layer (DOL) than is allowable in glasses with stress profiles that follow the complementary error function at a given level of stored tension. In some instances, a buried layer or local maximum of increased compression, which can alter the direction of cracking systems, is present within the depth of layer. Theses compressive stress profiles are achieved by a three step process that includes a first ion exchange step to create compressive stress and depth of layer that follows the complimentary error function, a heat treatment at a temperature below the strain point of the glass to partially relax the stresses in the glass and diffuse larger alkali ions to a greater depth, and a re-ion-exchange at short times to re-establish high compressive stress at the surface. | 08-29-2013 |
20130236666 | GLASS WITH SURFACE AND CENTRAL REGIONS UNDER COMPRESSION - A glass article having an engineered stress profile. The central or core region of the glass is in compression and the surface or outer region of the glass is either under neutral stress or in compression. The outer surface region and the core region are separated by an intermediate region that is under tension. A flaw that penetrates the outer region in compression will propagate in the underlying tensile intermediate layer, but will not penetrate though the compressive core region of the glass. The compressive core region prevents flaws from penetrating through the thickness of the glass. | 09-12-2013 |
