Abstract: This application relates to a part that includes a metal oxide layer having pore structures. In some embodiments, dye molecules having aromatic rings can be disposed within at least one of the pore structures. Additionally, the at least one pore structures can include dispersion molecules, where the dispersion molecules form non-covalent interactions with the dye molecules. By forming non-covalent interactions between the dye molecules and the dispersion molecules, the aromatic rings of the dye molecules are prevented from forming other non-covalent interactions with other dye molecules. Additionally, techniques for chemically stabilizing the color dye bath for dyeing anodized parts are also described.

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.

Abstract: A method for providing a surface finish to a metal part includes both diffusion hardening a metal surface to form a diffusion-hardened layer, and oxidizing the diffusion-hardened layer to create an oxide coating thereon. The diffusion-hardened layer can be harder than an internal region of the metal part and might be ceramic, and the oxide coating can have a color that is different from the metal or ceramic, the color being unachievable only by diffusion hardening or only by oxidizing. The metal can be titanium or titanium alloy, the diffusion hardening can include carburizing or nitriding, and the oxidizing can include electrochemical oxidization. The oxide layer thickness can be controlled via the amount of voltage applied during oxidation, with the oxide coating color being a function of thickness. An enhanced hardness profile can extend to a depth of at least 20 microns below the top of the oxide coating.

Abstract: Anodic oxide coatings that provide corrosion resistance to parts having protruding features, such as edges, corners and convex-shaped features, are described. According to some embodiments, the anodic oxide coatings include an inner porous layer and an outer porous layer. The inner layer is adjacent to an underlying metal substrate and is formed under compressive stress anodizing conditions that allow the inner porous layer to be formed generally crack-free. In this way, the inner porous layer acts as a barrier that prevents water or other corrosion-inducing agents from reaching the underlying metal substrate. The outer porous layer can be thicker and harder than the inner porous layer, thereby increasing the overall hardness of the anodic oxide coating.

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: Dyed anodic oxides having modified dye concentration profiles, and processes for forming the same, are described. The modified dye concentration profiles can be characterized as having a peak of dye concentration beyond at least a specified distance from an outer surface of an anodic oxide. The modified dyed anodic oxides less prone to discoloration, color fading and other cosmetic defects compared to conventionally dyed anodic oxides. The dyed anodic oxides are well suited for implementation on metal surfaces of consumer products, such as consumer electronic products.

Abstract: This application relates to a method for forming an enclosure for a portable electronic device, the enclosure including a metal substrate that is overlaid by an anodized layer. The method includes dyeing the anodized layer by exposing pores of the anodized layer to a dye. The method further includes sealing the dye within the pores by exposing the anodized layer to a zinc-based sealing solution, where an external surface of the anodized layer having the pores that are sealed includes an amount of zinc between about 3 wt % to about 6 wt %.

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.
