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 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: Methods and compositions of applying metallic coatings, or altering metallic compositions, are described. Metallic coatings are deposited on metallic substrates and treated with pulsed radiation, such a pulsed electron beam. The resulting metal substrate can have a metallic coating and/or altered surface chemistry.
