Abstract: Textured enclosure components formed from zirconia-based ceramics are disclosed. The texture of the enclosure component can give a matte appearance to an exterior surface of an electronic device. The texture of the enclosure component may also be configured so that it has one or more tactile properties suitable for use as a wearable device and can be readily cleaned.

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: The disclosure is directed to methods of forming glassy alloys. A glassy alloy is cold rolled at a temperature less than Tg of the glassy alloy to form a flattened glassy alloy. Then, the cold rolled glassy alloy is thermoplastically formed at a temperature above Tg of the glassy alloy. In certain embodiments, the flattened glassy alloy may have one or more shear bands and/or micro-cracks, and the thermoplastic forming may heal the shear bands and/or micro-cracks. The resulting glassy alloy may thereby have reduced or eliminated shear bands and/or micro-cracks.

Abstract: A method of manufacturing a housing of an electronic device includes applying a mask to a portion of a ceramic green body to define a masked portion and an unmasked portion, applying a pigment to the ceramic green body to color the unmasked portion, and sintering the ceramic green body to remove the mask and form a ceramic housing. The ceramic housing may comprise a first portion corresponding to the masked portion and having a first color, and a second portion corresponding to the unmasked portion and having a second color different from the first color.

Abstract: Embodiments herein relate to methods and apparatuses for casting of BMG-containing parts. The surfaces of the mold that come into contact with the molten amorphous alloy comprise an amorphous material. In accordance with the disclosure, the mold may be coated with an amorphous material, e.g., to reduce, minimize, or eliminate crystallization of the molded BMG-containing part. The surfaces of the mold are coated, in certain aspects, so as to reduce or eliminate potential grain-boundary nucleation sites for BMG crystallization. The amorphous material may be selected based on the particular molten amorphous alloy to be cast, e.g., based on the wetting properties, the melting and cooling properties, etc.

Abstract: An electronic device includes one or more emitters, one or more receivers, and a glass or other breakable external component, such as the cover glass of a display. The emitters emit one or more waves that travel via the glass. The receivers are configured to receive the waves from the glass. Damage to the glass, cracks for example, interrupts and/or interferes with travel of the waves via the glass. The electronic device determines the presence and/or absence of damage to the glass based on whether or not the receivers receive the waves. The location of damage to the glass may also be determined.
