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: 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: A process is disclosed for minimizing the difference in thermal expansivity between a porous anodic oxide coating and its corresponding substrate metal, so as to allow heat treatments or high temperature exposure of the anodic oxide without thermally induced crazing. A second phase of higher thermal expansivity than that of the oxide material is incorporated into the pores of the oxide in sufficient quantity to raise the coating's thermal expansion coefficient. The difference in thermal expansion between the anodic oxide coating and underlying metal substrate is reduced to a level such that thermal exposure is insufficient for any cracking to result. The second phase may be an electrodeposited metal, or an electrophoretically deposited polymer. The second phase may be uniformly deposited to a certain depth, or may be deposited at varying amounts among the pores.

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: 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: Micro additions of certain elements such as zirconium or titanium are added to high strength aluminum alloys to counter discoloring effects of other micro-alloying elements when the high strength alloys are anodized. The other micro-alloying elements are added to increase the adhesion of an anodic film to the aluminum alloy substrate. However, these micro-alloying elements can also cause slight discoloration, such as a yellowing, of the anodic film. Such micro-alloying elements that can cause discoloration can include copper, manganese, iron and silver. The micro additions of additional elements, such as one or more of zirconium, tantalum, molybdenum, hafnium, tungsten, vanadium, niobium and tantalum, can dilute the discoloration of the micro-alloying elements. The resulting anodic films are substantially colorless.

Abstract: Methods of forming anodic oxide coatings on high strength aluminum alloys are described. Methods involve preventing or reducing the formation of interface-weakening species, such as zinc-sulfur compounds, at an interface between an anodic oxide coating and underlying aluminum alloy substrate during anodizing. In some embodiments, a micro-alloying element is added in very small amounts to an aluminum alloy substrate to prevent enrichment of zinc at the anodic oxide and substrate interface, thereby reducing or preventing formation of the zinc-sulfur interface-weakening species. In some embodiments, a sulfur-scavenging species is added to an aluminum alloy substrate to prevent sulfur from a sulfuric acid anodizing bath from binding with zinc and forming the zinc-sulfur interface-weakening species at the anodic oxide and substrate interface. In some embodiments, a micro-alloying element and a sulfur-scavenging species are added to an aluminum alloy substrate. Resultant anodic oxide coatings have minimal or no discoloration.
