Abstract: Anodic oxide coatings and methods for forming anodic oxide coatings on metal alloy substrates are disclosed. Methods involve post-anodizing processes that improve the appearance of the anodic oxide coating or increase the strength of the underlying metal alloy substrates. In some embodiments, a diffusion promoting process is used to promote diffusion of one or more types of alloying elements enriched at an interface between the anodic oxide coating and the metal alloy substrate away from the interface. The diffusion promoting process can increase an adhesion strength of the anodic oxide film to the metal alloy substrate and reduce an amount of discoloration due to the enriched alloying elements. In some embodiments, a post-anodizing age hardening process is used to increase the strength of the metal alloy substrate and to improve cosmetics of the anodic oxide coatings.

Abstract: This disclosure relates to rapid and repeatable tests that can be used to evaluate the interfacial adhesion of coatings to substrates. In particular embodiments, tests are used to assess the resistance of anodic oxides to delamination from aluminum substrates. The tests can be conducted using standard hardness test equipment such as a Vickers indenter, and yield more controlled, repeatable results than a large sample of life-cycle tests such as rock tumble tests. In particular embodiments, the tests involve forming an array of multiple indentations within the substrate such that stressed regions where the coating will likely delaminate are formed and evaluated.

Abstract: This application relates to a multi-piece enclosure for a portable electronic device (102, 104, 106). The enclosure includes a metal part (240) including a metal substrate (204) and a metal oxide layer (206) overlaying the metal substrate (204), the metal oxide layer (206) having an external surface (202) that includes openings that lead into undercut regions (WU). The openings are characterized as having a first width, and the undercut regions (WU) are characterized as having a second width that is greater than the first width. The enclosure further includes a non-metallic bulk layer (252) including protruding portions that extend into the undercut regions (WU) such that the non-metallic bulk layer (252) is interlocked with the metal part (240).
