▎ 摘　　要

NOVELTY - Graphene coated metallic material product includes metal products with graphene coat covering the surface along the outer shape of the metal product. The graphene coat is formed by thermal chemical vapor deposition method. USE - Graphene coated metallic material product. ADVANTAGE - The metallic material product has high quality graphene along the outer shape with improved material, physical, chemical, mechanical and electrical properties. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for manufacturing a graphene-coated metal product, which involves increasing the temperature in the chamber in which the metal product is located to the graphene growth temperature while supplying a mixed gas containing hydrogen and an inert gas, heating at the growth temperature while additionally supplying hydrocarbon gas in the chamber in the mixed gas atmosphere for carbon decomposition from the hydrocarbon gas on the surface along the outline of the metal product to grow into graphene, and cooling the temperature in the chamber to room temperature in the mixed gas atmosphere.
