  • Patent number: 10975482
    Abstract: The invention discloses a self-derivative iron-containing nickel anode for alkaline water electrolysis and its preparation method. The anode comprises a nickel substrate and catalytic material layer. The catalytic layer is disposed on and integrated with the surface of the nickel substrate. The catalytic layer contains nickel oxide with iron components. The nickel oxide results from the reaction of the surface layer of the nickel substrate with an oxidant-rich alkaline solution and forms a nanosheet array layer. A nickel-oxidation state containing the iron component is formed by electrochemically induced iron-ion corrosion of the nickel-oxidation state. The invention can effectively reduce the potential difference between the anode and cathode of an electrolysis cell, thereby significantly reduces energy consumption and improves the efficiency of water electrolysis.

  • 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: Methods of reducing an initial cross-sectional area of a hole in a component to a predetermined cross-sectional area including preparing a composition comprising at least an aluminum alloy with a melting temperature higher than aluminum, applying the composition to an interior surface of the hole, and then heating the component to cause a metal within the component to diffuse from the component into the composition and react with the aluminum alloy in the composition to form a coating on the interior surface of the hole. The heating step is performed to selectively modify the initial cross-sectional area of the hole and thereby directly attain the predetermined cross-sectional area thereof.

  • Patent number: 8691028
    Abstract: A method for protecting a surface of an article includes preparing or otherwise providing a reactive solution of a form of polyaniline and an acid, thereafter applying the reactive solution to the surface of the article to form an adherent conversion coating on the surface, thereafter oxidizing the adherent conversion coating to form an oxidized coating, and thereafter contacting a chromate-free, corrosion inhibiting organic compound such as a salt of a dithiocarbamate or a salt of a dimercaptothiadiazole to the oxidized coating to form a fixed conversion coating on the surface of the article. The resulting article has the fixed conversion coating adhered to the surface of the article. The fixed conversion coating has a mixture of a reduced polyaniline salt, and a fixed disulfur-linked dithiocarbamate polymer or dimer.

  • Patent number: 8679586
    Abstract: The present invention relates to a method for improving the corrosion-protecting pre-treatment of metal surfaces and using rinse water in a manner to conserve resources in such a corrosion-protecting pre-treatment, comprising a conversion treatment step using an aqueous composition comprising at least 50 ppm of the elements B, Si, Ti, Zr and/or Hf in the form of water-soluble compounds at a pH value of 3 to 5.5, wherein a minimum fraction of 10 ppm of the elements B, Si, Ti, Zr and/or Hf in the form of water-soluble compounds is present in the last pre-rinse step and a portion of the aqueous composition of the conversion treatment step is contained in the first post-rinse step. The resource-conserving use of the rinse water is accomplished according to the invention by way of a cascaded return of rinse water from the last rinse step to the first rinse step.

  • Patent number: 8617321
    Abstract: The present invention provides a surface treatment method for an aluminum alloy and a surface treatment method for a magnesium alloy, which enable providing the surface of an aluminum alloy containing magnesium or the surface of a magnesium alloy with sufficient corrosion resistance to corrosive gases, while preventing the surface from scattering magnesium therefrom even when used in a vacuum at a temperature of not less than 300° C. In this method, a carbon fluoride compound is applied over the surface of the aluminum alloy containing magnesium or the surface of the magnesium alloy, followed by heating in an oxygen atmosphere, thereby forming a fluoride passivation film.

  • Patent number: 8608869
    Abstract: A method is disclosed for improving the corrosion behavior of cast magnesium alloy articles in which the magnesium alloy comprises an average composition of more than about 5 per cent by weight of aluminum. A microstructure with regions of varying aluminum content is developed during solidification. The microstructure comprises magnesium-rich grains generally surrounded by an aluminum-enriched phase on the boundaries between adjacent grains. The magnesium-rich grain interiors are then selectively chemically or electrochemically attacked to leave a more corrosion resistant aluminum-enriched surface on the articles. The corrosion resistance of the articles may be further enhanced by one or more of anodizing, aluminizing or painting the corrosion-resistant aluminum-enriched surface.

  • Patent number: 8506728
    Abstract: In a process which is before a treatment process of forming a chemical conversion, TiO2 fine particles as an electron releasing-related substance (electron releasing substance) are attached onto a surface of a vehicle body. Then, a chemical conversion treatment is applied to the vehicle body having the TiO2 fine particles attached thereto. Thereby, an energy band gap of a finally-formed chemical conversion film can be smaller than that of a chemical conversion film formed by using only a chemical conversion treatment agent. Accordingly, the number of electrons (free electrons) which can be supplied onto the surface of a chemical conversion film can be increased during a voltage application in an electrodeposition coating process, and reducing reaction at a cathode can be promoted.
