Publication number: 20180313728Abstract: Apparatus and methods for impact testing of a transparent substrate are provided. The apparatus includes a base (110) for receiving the transparent substrate (112), the base having a curved surface (124) about which the transparent substrate is bent by a first fixture (130) and a second fixture (132). An abrasive sheet (136) is disposed between the transparent substrate and an impacting object (138) which is released from above the substrate such that the force from the impacting object causes damage to the transparent substrate while the transparent substrate is bent about the curved surface.Type: ApplicationFiled: October 28, 2016Publication date: November 1, 2018Inventors: Benedict Osobomen Egboiyi, Kevin Barry Reiman, Brian Paul Strines

Patent number: 9908810Abstract: Chemically strengthened glass articles having at least one deep compressive layer extending from a surface of the article to a depth of at least about 45 ?m within the article are provided. In one embodiment, the compressive stress profile includes a single linear segment extending from the surface to the depth of compression DOC. Alternatively, the compressive stress profile includes two linear portions: the first portion extending from the surface to a relatively shallow depth and having a steep slope; and a second portion extending from the shallow depth to the depth of compression. The strengthened glass has a 60% survival rate when dropped from a height of 80 cm in an inverted ball drop test and an equibiaxial flexural strength of at least 10 kgf as determined by abraded ring-on-ring testing. Methods of achieving such stress profiles are also described.Type: GrantFiled: October 24, 2016Date of Patent: March 6, 2018Assignee: CORNING INCORPORATEDInventors: Jaymin Amin, Benedict Osobomen Egboiyi, Jonathan David Pesansky, Kevin Barry Reiman, Rostislav Vatchev Roussev, Brian Paul Strines

Publication number: 20170369989Abstract: Provided herein are ion-implanted glass based articles with improved flaw suppression properties. The ion-implanted glass based articles generally have a final indent fracture threshold (IFT) load of at least 650 grams, and/or a scratch threshold force of at least 10 N, which represents at least 1.25-fold enhancement compared to the glass based article prior to ion-implantation. Factors affecting the efficacy of the ion implantation process can include the IFT load of the starting glass or glass ceramic substrate (native IFT load), ion type, ion dose, implant energy, beam current, and glass temperature.Type: ApplicationFiled: June 22, 2017Publication date: December 28, 2017Inventors: Sarko Cherekdjian, Benedict Osobomen Egboiyi, William Brashear Mattingly, III, Michael Yoshiya Nishimoto, Toshihiko Ono, Parkash Chandra Panda, Trevor Edward Wilantewicz

Publication number: 20170129803Abstract: Chemically strengthened glass articles having at least one deep compressive layer extending from a surface of the article to a depth of layer DOL of about 130 ?m up to about 175 ?m or, alternatively, to a depth of compression (DOC) in a range from about 90 ?m to about 120 ?m within the article. The compressive layer has a stress profile that includes a first substantially linear portion extending from a relatively shallow depth to the DOL or DOC and a second portion extending from the surface to the shallow depth. The second portion is substantially linear at a depth from 0 ?m to 5 ?m and has a steeper slope than that of the first portion of the profile. Methods of achieving such stress profiles are also described.Type: ApplicationFiled: January 26, 2017Publication date: May 11, 2017Inventors: Jaymin Amin, Benedict Osobomen Egboiyi, Pascale Oram, Jonathan David Pesansky, Kevin Barry Reiman, Rostilav Vatchev Roussev, Vitor Marino Schneider, Brian Paul Strines
