    Abstract: A method of forming a unitary sintered body can include cutting a first portion and a second portion from a sheet of feedstock. The feedstock can include ceramic or metallic particles suspended in a binder. The first portion can be positioned in contact with the second portion and the portions can be sintered together to form the unitary body.

    Abstract: Anodized substrates having laser markings and methods for forming the same are described. According to some embodiments, the methods involve forming a feature on a substrate using a laser prior to anodizing. The laser energy and pulse width can be chosen so as to provide a particular topology to a surface of the substrate that, after anodizing, absorbs incoming light and imparts a dark appearance to the feature. In some cases, the methods involve forming a coarse oxide layer, which is removed prior to anodizing. Since the laser marking is performed prior to anodizing, the anodized substrates are free from laser-induced cracks, thereby making the anodized substrates more corrosion resistant than conventional laser-marked anodized substrates. The techniques are well suited for forming features on consumer products that may be exposed to water or other corrosion-inducing agents.

    Abstract: Methods of forming anodic oxide coatings on certain 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.
