Abstract: A method of forming a part can include selectively activating one or more lasers of a laser array comprising at least 100 lasers based at least partially on a geometry of the part being formed. The method can further include scanning laser spots over a powder bed, the laser sports generated by the activated lasers, and selectively sintering a powder contained in the powder bed with the laser spots to form the part.

Abstract: This application relates to a composite part that can include a non-metal layer having attachment features, and a metal part that is joined with the non-metal layer. The metal part can include a plurality of interlocking structures that are disposed at an external surface of the metal part, where each of the interlocking structures can include an opening characterized as having a first width, and an undercut region, where the opening leads into the undercut region, and the undercut region is characterized as having a second width that is greater than the first width such that the undercut region captures and retains one of the attachment features of the non-metal layer.

Abstract: Sealed anodic coatings that are resistant to leaching of nickel and nickel-containing products and methods for forming the same are described. Methods involve post-sealing thermal processes to remove at least some of the leachable nickel from the sealed anodic coatings. In some embodiments, the post-sealing thermal processes involve immersing the sealed anodic coating within a heated solution so as to promote diffusion of the leachable nickel out of the sealed anodic coatings and into the heated solution. The resultant sealed anodic coating is pre-leached of nickel and is therefore well suited for many consumer product applications. In some embodiments, a post-sealing thermal process is used to further hydrate and seal the sealed anodic coating, thereby repairing structural defects within the sealed anodic coating.

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.
