  • Patent number: 9840764
    Abstract: A method of fabricating transition metal dichalcogenides includes a preparing step, a steaming step and a depositing step. The preparing step is performed for providing a transition metal substrate, a reactive gas and a solid chalcogenide. The steaming step is performed for heating the solid chalcogenide to generate a chalcogenide gas in a steaming space. The depositing step is performed for introducing the reactive gas into the chalcogenide gas to ionize the chalcogenide gas so as to generate a chalcogenide plasma in a depositing space. The depositing step is performed under a process vacuum pressure from low vacuum pressure to atmospheric pressure. The reactive gas and the chalcogenide gas are flowed from top to bottom through a top of the transition metal substrate. The loading substrate is heated at a loading substrate temperature, and the steaming space is different from the depositing space.

  • Patent number: 8916005
    Abstract: A slurry and slurry coating process for forming a diffusion aluminide coating on a substrate, including internal surfaces within the substrate. The process involves preparing a slurry of a powder containing a metallic aluminum alloy having a melting temperature higher than aluminum, an activator capable of forming a reactive halide vapor with the metallic aluminum, and a binder containing an organic polymer. The slurry is applied to surfaces of the substrate, which is then heated to burn off the binder, vaporize and react the activator with the metallic aluminum to form the halide vapor, react the halide vapor at the substrate surfaces to deposit aluminum on the surfaces, and diffuse the deposited aluminum into the surfaces to form a diffusion aluminide coating. The process can be tailored to selectively produce an inward or outward-type coating. The binder burns off to form an ash residue that can be readily removed.

    Abstract: Provided are a method for producing powder for a magnet, and methods for producing a powder compact, a rare-earth-iron-based alloy material, and a rare-earth-iron-nitrogen-based alloy material. Magnetic particles constituting the powder each have a texture in which grains of a phase of a hydride of a rare-earth element are dispersed in a phase of an iron-containing material. The uniform presence of the phase of the iron-containing material in each magnetic particle results in powder having excellent formability, thereby providing a powder compact having high relative density. The powder is produced by heat-treating rare-earth-iron-based alloy powder in a hydrogen atmosphere to separate the rare-earth element and the iron-containing material and then forming a hydride of the rare-earth element. The powder is compacted. The powder compact is heat-treated in vacuum to form a rare-earth-iron-based alloy material.

  • Patent number: 8277577
    Abstract: The invention relates to a method for obtaining a surface of a titanium-based metal implant intended to be inserted into bone tissue, comprising: (a) projecting particles of aluminum oxide under pressure on the external area of the implant; (b) chemically treating the sandblasted external area of the implant with an acid composition comprising sulfuric acid and hydrofluoric acid; and (c) thermally treating the sandblasted external area of the implant by heating at a temperature of 200-450° C. for 15-120 min. The invention likewise defines a metal implant having said surface. The surface thus obtained has good micrometer-scale roughness with a suitable morphology, as well as a composition which is virtually free of impurities and a thickness which is approximately three times the thickness of conventional surfaces, which characteristics provide it with very good osseointegration properties.

    Abstract: The present invention provides a powder for a magnet which can form a rare earth magnet having excellent magnetic characteristics and which has excellent moldability, a method for producing the powder for a magnet, a powder compact, and a rare earth-iron-boron-based alloy material. Magnetic particles constituting a powder for a magnet each include a structure in which a particle of a phase 3 of a hydrogen compound of a rare earth element is dispersed in a phase 2 of an iron-containing material. Since the phase 2 of the iron-containing material is uniformly present in each of the magnetic particles 1, the powder has excellent moldability and easily increases the density of a powder compact 4.
