▎ 摘　　要

NOVELTY - A graphene-containing carbonaceous component/ceramic assembly (20) comprises graphene aggregate and a ceramics component comprising ceramics-containing nitrogen bonded with graphene-containing carbon, and an active metal nitride layer is formed at the assembly of graphene containing-carbonaceous component and ceramic component. The thickness of the active metal nitride layer is 0.05-2 mu m. USE - Graphene-containing carbonaceous component/ceramic assembly used for copper/graphene-containing carbonaceous component/ceramic assembly used in engine compartment and cooling-heat cycle. ADVANTAGE - The graphene-containing carbonaceous component/ceramic assembly has improved bonding rigidity and excellent cooling-heat cycle reliability. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for copper/graphene-containing carbonaceous component/ceramic assembly, which comprises copper component comprising copper or copper alloys, the graphene-containing carbonaceous component comprising graphene aggregate bonded with ceramic component comprising ceramics-containing nitrogen. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of assembly of graphene-containing carbonaceous component of graphene-containing carbonaceous member/ceramic assembly and ceramic component.
