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: A method of forming a component can include electrochemically depositing a metallic material onto a carrier component to a thickness of greater than 50 microns. The metallic material can include crystal grains and at least 90% of the crystal grains can include nanotwin boundaries. The metallic material can include at least one of copper or silver.

Abstract: Oxide coatings that reduce or eliminate the appearance of thin film interference coloring are described. In some embodiments, the oxide coatings are configured to reduce the appearance of fingerprints. In some cases, the oxide coatings are sufficiently thick to increase the optical path difference of incident light, thereby reducing any inference coloring by the fingerprint to a non-visible level. In some embodiments, the oxide coatings have a non-uniform thickness that changes the way light reflects off of interfaces of the oxide coating, thereby reducing or eliminating any thin film interference coloring caused by the oxide coatings themselves or by a fingerprint.

Abstract: An electronic device can include a component including a first material joined to a component including a second, different material. The first material can include steel and copper, while the second material can include aluminum. The first material can be joined to the second material by a pulsed laser welding process that forms an interface region having a ratio of an interface region length to a lateral length greater than about 1.4.

Abstract: Composite coatings having improved abrasion and dent resistance are described. According to some embodiments, the composite coatings include an outer hard layer and an intermediate layer between the outer hard layer and a metal substrate. The intermediate layer can have a hardness that is less than the hard outer layer but greater than the metal substrate. In this arrangement, the intermediate layer can act as a structural support that resists plastic deformation when an impact force is applied to the coating. In some embodiments, the intermediate layer is composed of a porous anodic oxide material. In some embodiments, the outer hard layer is composed of a ceramic material or a hard carbon-based material, such as diamond-like carbon.
