Abstract:
The main purpose of the present invention is to provide a cermet composite material capable of improving the bond strength between a cermet portion and a non-cermet portion even without being subjected to a high-temperature heat treatment. This cermet composite material is characterized by having a cermet portion where hard carbides are dispersed in a metal phase and a non-cermet portion formed from an Ni-based alloy containing 50 mass% or more of Ni, wherein: the cermet portion is additively fabricated on the non-cermet portion; the cermet portion and the non-cermet portion have therebetween an intermediate layer in which the constituents of the cermet portion and the non-cermet portion are mixed; the non-cermet portion is formed from the Ni-based alloy containing Ti in the range of 3.0 mass% to 15.0 mass%, or from the Ni-based alloy containing Ti in the range of 0.5 mass% to less than 3.0 mass% and the total of 4 mass% to 5 mass% of Nb and Ta.
