▎ 摘  要

NOVELTY - A graphene-coated component consists of a graphene film provided on the surface of a metallic substrate of a desired shape. The substrate consists of a carbon formed into a solid solution. The graphene film consists of a solid-solution carbon precipitated on the surface of substrate. USE - Graphene-coated component. Uses include but are not limited to low gas-emission ultra-high vacuum material, structural components used for ultra-precise electron-spectroscopy measurement in ultra-high vacuum, electronic-device substrate, and electrodes of batteries. ADVANTAGE - The graphene-coated component consists of a homogeneous graphene film. The component has excellent oxidation resistance and stain resistance, low gas absorptivity, low gas-emission property, and low secondary electron-emission property. The component can be manufactured reliably. Even when the graphene film peels, it can be re-coated by reheating treatment. The component provides electronic-device substrates having high mobility. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for manufacture of graphene-coated component, which involves heating metallic substrate at 600-950 degrees C in vacuum, depositing carbon on the surface and producing graphene, and forming graphene film by rapidly cooling to 400 degrees C or less at 2x 10-20x 10 degrees C/second.
