Abstract: This application relates to a part for a portable electronic device. The part includes a titanium alloy substrate including a network of branching channels. The branching channels include a first channel and a second channel, where the first channel is defined by a first channel wall that extends away from a first opening in the exterior surface, and the second channel is defined by a second channel wall that extends away from a second opening in the first channel wall.

Abstract: An enclosure for a portable electronic device can include a titanium substrate defining a textured surface and a nominal surface. The titanium substrate can include a first region that extends above the nominal surface and a second region adjacent to the first region and extending below the nominal surface. A separation distance between an apex of the first region and a bottom of a trough defined by the second region can be at least 1 micrometer. A metal oxide layer can overlay the trough defined by the second region.

Abstract: This application relates to a multi-piece enclosure for a portable electronic device. The enclosure includes a metal part including a metal substrate and a metal oxide layer overlaying the metal substrate, the metal oxide layer having an external surface that includes openings that lead into undercut regions. The openings are characterized as having a first width, and the undercut regions are characterized as having a second width that is greater than the first width. The enclosure further includes a non-metallic bulk layer including protruding portions that extend into the undercut regions such that the non-metallic bulk layer is interlocked with the metal part.

Abstract: Anodized aluminum alloys that are resistant to corrosion are described. According to some embodiments, the anodized aluminum alloys include very small amounts, even trace levels, of corrosion resistant elements with higher Gibbs free energies for oxide formation than aluminum. If the aluminum alloy includes high levels of zinc, the corrosion resistant elements can also have higher Gibbs free energies for oxide formation than zinc. The corrosion resistant elements can accumulate at an interface region of the substrate near the anodic film during the anodizing process, thereby significantly changing the alloy composition in this interface region providing surprising high resistance to certain forms of corrosion. The type and amount of corrosion resistant elements can depend on particular application requirements. In some cases, the anodized aluminum alloys are used as cosmetic appealing housing for consumer electronic products.
