  • Patent number: 7906219
    Abstract: A metallic glass laminate of the present invention is characterized in that a metallic glass layer of amorphous phase is formed on the substrate surface, and there is no continuous pore (pinhole) through the metallic glass layer. The metallic glass laminate is preferably obtained by solidification and lamination of at least part of the metallic glass powder in the molten state or in the supercooled liquid state on the substrate surface. Because of the dense metallic glass layer of homogenous amorphous phase, the functionalities of metallic glass such as corrosion resistance and wear resistance can be satisfactorily provided. A thick and a large-area metallic glass layer can be formed. The metallic glass layer can also be formed into various shapes within the supercooled liquid temperature range. In addition, a metallic glass bulk can be obtained by removing the substrate.

  • Publication number: 20110003172
    Abstract: Vapor plasma deposition of titanium (Ti) metal onto a substrate forms a structured surface that exhibits enhanced cell attachment properties. Initially deposited round nanoparticulate surface structures develop tentacles with a spine or thorn-like appearance upon continued deposition under special conditions. The density and size of the formed spinulose particles can be controlled by timing the deposition intervals. A significant increase in osteoblast, fibroblast and endothelial cell attachment is observed on Ti spinulose surfaces compared to attachment on nanoparticulate surfaces lacking spinulous nanostructure.

  • Patent number: 7597987
    Abstract: An Au plated film 12 is formed on the surface of a plate-formed metal base 13 composed of a metal less noble than Au, and the product is cut along a planned cutting line 18 reflecting a contour of a desired component, to thereby form a separator 10. Thus-formed separator 10 has the Au plated film 12 formed on the main surface 10a thereof, and has a cutting plane 16 formed as an end face 16 stretched up to the main surface 10a. The metal base 13 exposes in a part of the cutting plane 16, in a width of the exposed region of 1 mm or less. This is successful in providing a metal component for fuel cell which is satisfactory in the corrosion resistance and allows easy fabrication at low costs, a method of manufacturing the same, and also in providing a fuel cell having thus-fabricated metal component for fuel cell.

    Abstract: An outwardly grown diffusion aluminide bondcoat is formed on a superalloy substrate and has higher concentrations of Al and Pt and lower concentrations of harmful impurities (e.g. Mo, W, Cr, Ta, S, etc.) at an outermost region of the bondcoat than at an innermost region thereof adjacent the substrate. The bondcoat is pretreated prior to deposition of a ceramic thermal insulative layer in a manner that reduces grain boundary ridges on the outermost bondcoat surface without adversely affecting the outermost region thereof, and then is heat treated to thermally grow a stable alpha alumina layer on the bondcoat prior to deposition of a ceramic layer.
