  • Patent number: 11925922
    Abstract: The present invention relates to a method of improving the corrosion resistance of a metal substrate surface using an oxygen reduction catalyst, which may improve the corrosion resistance of the metal substrate surface by coating the metal substrate surface with the oxygen reduction catalyst so that the metal substrate surface is changed to a passive state through the action of the oxygen reduction catalyst in an environment in which a stable oxide layer is not spontaneously formed on the metal substrate surface. The present invention has an advantage in that it can dramatically improve the corrosion resistance of the metal substrate under a corrosive environment by allowing a recoverable oxide layer to be formed on the metal substrate surface through the action of the oxygen reduction catalyst, applied to the surface, even in an environment in which an oxide layer is not spontaneously formed on the metal substrate.

  • Patent number: 8124176
    Abstract: A polymer assisted deposition process for deposition of metal nitride films and the like is presented. The process includes solutions of one or more metal precursor and soluble polymers having binding properties for the one or more metal precursor. After a coating operation, the resultant coating is heated at high temperatures under a suitable atmosphere to yield metal nitride films and the like. Such films can be conformal on a variety of substrates including non-planar substrates. In some instances, the films can be epitaxial in structure and can be of optical quality. The process can be organic solvent-free.

  • Patent number: 8084105
    Abstract: Methods for forming boron-containing films are provided. The methods include introducing a boron-containing precursor and a nitrogen or oxygen-containing precursor into a chamber and forming a boron nitride or boron oxide film on a substrate in the chamber. In one aspect, the method includes depositing a boron-containing film and then exposing the boron-containing film to the nitrogen-containing or oxygen-containing precursor to incorporate nitrogen or oxygen into the film. The deposition of the boron-containing film and exposure of the film to the precursor may be performed for multiple cycles to obtain a desired thickness of the film. In another aspect, the method includes reacting the boron-containing precursor and the nitrogen-containing or oxygen-containing precursor to chemically vapor deposit the boron nitride or boron oxide film.

  • Patent number: 8039045
    Abstract: An object of the present invention is to provide a plating method on a glass base plate. The method allows forming a plating film on a base plate composed of a glass material with excellent adhesivity and homogeneity by means of an electroless plating method even to a thickness of 1 ?m or more. Before forming a plating film by a step of electroless plating S6, a surface treatment process is conducted on a surface of the base plate composed of a glass material. The surface treatment process comprises at least a step of glass activation treatment S2 to increase quantity of silanol groups on the surface of the base plate at least by a factor of two using an aqueous solution of diluted acid, a step of silane coupling agent treatment S3, a step of palladium catalyst treatment S4, and a step of palladium bonding treatment S5.

A plurality of small crystalline glass masses 12 are accumulated and leveled in a fireproof mold coated with a mold release agent, and two crystalline glass plates 14A and 14B cut in an S shape are placed on the accumulated surface of the small crystalline glass masses 12 with the cut faces tightly bonded. A heat treatment is then performed to obtain a crystallized glass article having patterns. The crystalline glass plate can be cut into any shape to tightly bond the cut faces, and therefore the obtained crystallized glass articles have different patterns like natural-marble-like patterns, human figure patterns, animal patterns, etc. The invention also discloses a method of producing crystallized articles having patterns.
