Abstract: A housing for a portable electronic device is disclosed. The housing is composed of yttria-sensitized zirconia. Yttria-sensitized zirconia has from about 1.5 to about 2.5 mole percent yttria, and more typically about 2 mole percent yttria, and most typically 2 mole percent yttria, in zirconia. Yttria-sensitized zirconia is both tough and able to limit the formation and propagation of micro-cracks. Methods for manufacturing yttria-sensitized zirconia composed housings are also disclosed.

Abstract: A system for heat treating sapphire components to increase strength while maintaining the optical finish and/or transparency of the component. The system may include a fixture positioned in a furnace and configured to suspend an array or group of sapphire components. The fixture may include notches or other features to assist in locating and positioning the sapphire components. Shield elements or enclosures may also be interspersed with the sapphire components and may help produce a more uniform heat distribution and protect the sapphire components from emissions or deposits. Some aspects are directed to a sleeve tool and fixture jig that can be used to assemble the sapphire components onto the fixture in a way that reduces the risk of marring or otherwise damaging the sapphire components.

Abstract: Glass articles having a base layer formed of glass and having a first compressive stress, an adjacent compression layer formed in the glass and having a second compressive stress, and a witness layer formed in the glass adjacent the compression layer and having a third compressive stress. The first, second and third compressive stresses all differing from one another. The witness layer also having a higher index of refraction than an index of refraction for the base or compression layers. Methods for manufacturing and methods of quality control that include the use of the witness layer are also disclosed.

Abstract: Glass articles and methods for producing glass articles for a portable electronic device are disclosed. Properties of the glass articles, such as cover members, are improved through chemical strengthening, thermoforming, or a combination thereof. The glass articles may include barrier layers to prevent diffusion of ions between glass layers of the glass article, internal compressive stress regions, or a combination thereof.

Abstract: Methods and systems for localized strengthening of features of a component formed from a sapphire material include a combination of holistic heating and localized surface heating. In one example, the localized heating may occur via laser thermal, flame polishing, hot wire heating, plasma etching, or chemical treatment. By combining the localized surface heating with holistic heating, near-melt or melt processing in a localized area can be achieved while avoiding overheating of well-polished areas, and therefore minimizing defects that would otherwise be caused by excessive heating. This may be used for strengthening features of components formed from sapphire material that are difficult to polish, such as non-planar features.

Abstract: A sapphire sheet is laminated to a glass sheet with a gradient layer that transitions from a composition of predominantly Al2O3 at the sapphire sheet to a composition of predominantly SiO2 at the glass sheet. The gradient layer chemically bonds to both the sapphire sheet and the glass sheet and has no distinct interfaces.

Abstract: 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.
