GRAPHENE-CONTAINING CARBONACEOUS MEMBER/CERAMICS JOINT BODY AND COPPER/GRAPHENE-CONTAINING CARBONACEOUS MEMBER/CERAMICS JOINT BODY
To provide a graphene-containing carbonaceous member/ceramics joint body having excellent cold-heat cycle reliability, in which the ceramic member and the graphene-containing carbonaceous member containing graphene aggregates are firmly bonded and do not cause peeling even under a cold-heat cycle load.SOLUTION: A graphene-containing carbonaceous member/ceramics joint having a structure in which a graphene-containing carbonaceous member 21 containing a graphene aggregate and a ceramic member 25 made of nitrogen-containing ceramics are joined, where an active metal nitride layer 41 is formed on the bonding surface of the ceramic member 25 along the bonding interface 40 between the graphene-containing carbonaceous member 21 and the ceramic member 25, and the thickness of the active metal nitride layer is 0.05 μm to 2 μm.SELECTED DRAWING: Figure 4
【課題】セラミックス部材とグラフェン集合体を含有するグラフェン含有炭素質部材とが強固に接合されており、冷熱サイクル負荷時においても剥離が生じることがなく、冷熱サイクル信頼性に優れたグラフェン含有炭素質部材／セラミックス接合体を提供する。【解決手段】グラフェン集合体を含有するグラフェン含有炭素質部材２１と、窒素を含むセラミックスからなるセラミックス部材２５とが接合された構造のグラフェン含有炭素質部材／セラミックス接合体であって、グラフェン含有炭素質部材２１とセラミックス部材２５との接合界面４０において、セラミックス部材２５の接合面に活性金属窒化物層４１が形成されており、この活性金属窒化物層の厚さが０．０５μｍ以上２μｍ以下の範囲内とされている。【選択図】図４
