Title:
COMPOSITE BODY
Document Type and Number:
WIPO Patent Application WO/2016/185633
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing a composite body of a metal member and a cermet member, which exhibits sufficient joining strength. The solution is a composite body having a cermet member, a metal member and an intermediate member. The cermet member includes a cermet oxide phase and a cermet metal phase. The cermet oxide phase contains a Ni-containing oxide or an Fe-containing oxide. The cermet metal phase contains Ni. The intermediate layer contains Cu. The mass proportions of Cu in the cermet metal phase at points which are spaced apart by 10, 50, 100 and 1000 μm from the interface between the cermet member and the intermediate layer to the cermet member side are denoted by C10, C50, C100 and C1000 (mass%). When the mass proportions of Cu in the cermet oxide phase at points which are spaced apart by 10 and 100 μm from the interface to the cermet member side are denoted by M10 and M100 (mass%), C10 > C50 > C100 > C1000, and 5 > M10-M100 > -5.
