    Abstract: Provided is a method of manufacturing a palladium (Pd) thin film by using an electroless-plating method, the method including: manufacturing a reaction mixture by adding Pd salt and an alkaline pH regulator to an alcohol-water mixed solution; and forming a Pd thin film by loading and stirring the reaction mixture in a substrate. Accordingly, a Pd thin film having a surface enhancement Raman scattering (SERS) effect may be easily manufactured without having to use expensive additional equipment, such as a vacuum device, and in detail, electroless-plating may be performed even on an insulating substrate formed of, for example, glass. In addition, since a size of the Pd thin film manufactured on the substrate may be adjusted, the Pd thin film may be applied to various electrochemical products.

    Abstract: Systems and methods for fabricating multi-functional articles comprised of additively formed gradient materials are provided. The fabrication of multi-functional articles using the additive deposition of gradient alloys represents a paradigm shift from the traditional way that metal alloys and metal/metal alloy parts are fabricated. Since a gradient alloy that transitions from one metal to a different metal cannot be fabricated through any conventional metallurgy techniques, the technique presents many applications. Moreover, the embodiments described identify a broad range of properties and applications.

    Abstract: In conventional Al coated steel sheet, with the Al coating as it is, black discoloration cannot be prevented at 550° C. or more. For this reason, post annealing is used to form a barrier layer and suppress the formation of Fe—Al intermetallic compounds. However, with this method, there were the problems that the steel sheet became poor in workability and, further, high temperature, long time heating was required, so there were problems from the workability, economy, and environmental aspect. The present invention provides steel sheet which has a heat black discoloration resistance even at a 550° C. or more high temperature without additional annealing after Al coating and further is excellent in workability. That is, it is hot dip Al coated steel sheet which comprises steel sheet which contains predetermined ingredients of C, Si, P, S, Al, N, and O plus one or both of furthermore Ni: 0.01 to 0.1% or Cu: 0.01 to 0.1% and satisfies 10×C+Ni+Cu>0.

  • Patent number: 7694530
    Abstract: Chemical strengthening treatment is performed by first providing a granular chemical strengthening salt so as to prevent spread in atmosphere at the time of introduction of chemical strengthening salt in a treating vessel, introducing the chemical strengthening salt in a treating vessel, melting the chemical strengthening salt into molten chemical strengthening salt and bringing a glass disc into contact with the molten chemical strengthening salt. The granular chemical strengthening salt is, for example, one obtained by forming of a powdery chemical strengthening salt material into grains. A chemically strengthened glass substrate for magnetic disk can be obtained through the process of carrying out chemical strengthening treatment of magnetic disk glass substrates. A magnetic disk can be obtained by forming at least a magnetic layer on the chemically strengthened glass substrate for magnetic disk.

  • Patent number: 7687114
    Abstract: The invention relates to a method for metallic coating of fibers by liquid technique, in which a fiber, coated with a material forming a diffusion barrier with the metal, is drawn through a liquid metal bath to be coated therewith. The method is characterized in that prior to the passage of the fiber into the bath, the fiber is coated with a compound wettable by the metal. The coating of the fiber by the metal is facilitated by the presence of the compound, forming an interface wettable by the metal.

  • Patent number: 7681625
    Abstract: A wet filament winding method and apparatus for producing a consolidated metal matrix composite is described. The methods are directed to winding a softened metal infiltrated fiber bundle and layering the resulting softened metal infiltrated fiber bundle onto a rotating mandrel in a prescribed pattern on the surface of the mandrel to form a consolidated metal matrix composite. Upon cooling, the matrix metal solidifies and the resulting consolidated metal matrix composite may be removed from the mandrel. The consolidated metal matrix composites may be produced in a variety of shapes, such as cylinder, a tapered cylinder, a sphere, an ovoid, a cube, a rectangular solid, a polygonal solid, and panels.

  • Patent number: 7666476
    Abstract: A method of producing a metallized polymeric foam that produces an anti-microbial material using an advanced method of metallizing polymeric foam with a metal, such as silver. The foam material may be polyurethane, polyester, polyether, or a combination thereof. The method provides a 3-dimensional surface coating of the metal. The metallized substrate is durable and highly adherent. Such metallized foam is a highly effective filter and/or an anti-microbial product. The mechanism of filtration is mainly due to Vander Der Wal attraction. The anti-microbial activity may be due, in part, to the release of select metal ions as a response to stimuli.

  • Patent number: 7662438
    Abstract: The invention relates to a method for hot-dip coating a metal strand (1), especially a steel strip, according to which the metal strand (1) is vertically guided through a container (3) accommodating the molten coating metal (2) and through a guide channel (4) disposed upstream thereof. An electromagnetic field is generated in the area of the guide channel (4) by means of at least two inductors (5) disposed at both sides of the metal strand (1) to retain the coating material (2) in the container (3). In order to stabilize the metal strand (1) in a center position in the guide channel (4), an electromagnetic field, superimposing the electromagnetic field of the inductors (5), is generated by means of at least two additional coils (6) disposed at both sides of the metal strand (1).

  • Publication number: 20100015347
    Abstract: 2.1 The present invention pertains to a hot-dip coating device 100 for coating a metal strip with a molten metal 200. The metal strip is deflected in the molten metal 200 with the aid of a roll 120. The roll is rotatably supported in a support arm 105 by means of a bearing 144. The bearing is installed in a bearing chamber 142. In order to seal the bearing chamber 142 against an undesirable admission of the molten metal 200, a lock is arranged between the bearing chamber 142 and a roll passage 136 toward the molten metal 200 and acted upon with a gaseous medium under a gas pressure in order to seal the lock chamber 132 relative to the molten metal 200. 2.2 In order to lower the maintenance expenditures for the lock, the invention proposes to realize the lock chamber 132 in the form of a diving bell with a channel-shaped outlet 134 that is open relative to the surrounding molten metal 200.
