  • Solution composition for surface treatment of steel sheet and surface-treated steel sheet using same
    Patent number: 11939489
    Abstract: Provided is a composition for surface treatment of a steel sheet, the composition having excellent resistance to an acid, such as sulfuric acid, and to a coated steel sheet to which the composition for surface treatment is applied, wherein the composition for surface treatment comprises 30-50% wt % of colloidal silica containing 5-20 nm-sized silica, 40-60% wt % of silane containing three or more alkoxy groups, 5-15 wt % of an acrylate-based organic monomer, 0.01-1 wt % of an acid, and 1-15 wt % of a solvent.

  • Process for heat treatment nitriding in the presence of titanium and products produced thereby
    Patent number: 6645566
    Abstract: A method for nitriding a metallic base material at low temperatures in a salt bath containing electrolyzed titanium metal. A nitride coating of exceptional depth and hardness is obtained in a very short operating time due to the rapid nitriding process. The method is applicable to steel, titanium, aluminum and alloys thereof.

  • Process for providing a titanium dioxide layer on a material that contains a light absorbing substance and the product so formed
    Patent number: 6569386
    Abstract: A metallic compound layer exhibiting a photocatalytic activity function is formed on the surface of light absorbing material so as to provide the property of deodorizing air or an object coming in contact with the material. Preferably, the metallic compound layer is fixed on the surface of the light absorbing material. Alternatively, the metallic compound layer is formed as a material in which the surface region includes an outer portion mainly formed of a metallic mixture including a metallic oxide, such as titanium oxide. As a method of manufacturing the light absorbing material is coated with a metallic compound for improving photocatalytic activity, and then is processed into a desired shape.
