  • Patent number: 10590558
    Abstract: Techniques for forming an enclosure comprised of an aluminum alloy are disclosed. In some embodiments, aluminum ions and metal element ions can be dissolved in a non-aqueous ionic liquid in an electrolytic plating bath. A reverse pulsed electric current can facilitate in co-depositing the aluminum ions and the metal element ions onto a metal substrate. The resulting aluminum alloy layer can include nanocrystalline structures, which can impart the alloy layer with increased hardness and increased resistance to scratching, corrosion, and abrasion. In some embodiments, the metal element ion is chromium and the aluminum alloy layer includes a chromium oxide passivation layer formed via a passivation process. Subsequent to the passivation process, the formation of the chromium oxide layer does not impart a change in color to the aluminum alloy layer. In some embodiments, hafnium ions are co-deposited with aluminum ions to form an aluminum hafnium alloy.

    Abstract: A plating film is provided with enough hardness before anodic oxidation, which is hard to be damaged during handling, and also the production method of the plating film. This problem can be solved by an aluminum plating film with aluminum concentration of 98 wt. % or lower, and with a Vickers hardness of 250 or higher. The hardness is increased by containing oxygen, carbon, sulfur, and a halogen element as impurities. The impurity concentration is controlled by adjusting the current density, the plating temperature, or the plating bath composition.

  • Patent number: 8435645
    Abstract: A dielectric device comprises a substrate made of a metal and an oxide dielectric layer mounted on a surface of the substrate. The surface of the substrate has metal oxide regions distributed like islands, while the oxide dielectric layer is in close contact with the substrate through the metal oxide regions. Since adhesion is higher in an area where the substrate and the oxide dielectric layer are in close contact with each other through the metal oxide regions distributed like islands on the surface of the substrate, the adhesion between the substrate and oxide dielectric layer in the dielectric device is enhanced. As compared with a case where a rough surface is formed on a metal foil, the metal oxide region and the substrate are inhibited from forming a rough surface, whereby leakage characteristics can be kept from being deteriorated by the rough surface.

    Abstract: A component for high-temperature use comprises a metallic base material and a non-ferromagnetic protective layer arranged thereon, which is able to form a protective oxide layer on the component surface at temperatures between 600° C. and 1100° C. A sensor material is introduced into the protective layer, wherein, in the stated temperature range, the local magnetism, notably ferromagnetism or ferrimagnetism, at the site of the sensor material is dependent on the local concentration and/or composition of the material of the protective layer in the immediate vicinity of the sensor material and/or on the cumulative temperature-time curve at the site of the sensor material. The component can be examined non-destructively, from the outside, for the local magnetism in the protective layer, which is typically between 100 ?m and 500 ?m thick.
