ABSTRACT:
A composite construction1is obtained by coating the outer periphery of a core material2with a shell layer3. The core material2is composed of a first sintered body that is obtained by bonding, with a binder metal, a first hard particle composed of one or more of carbides, nitrides and carbonitrides of metals of Groups4a, 5aand6aof the Periodic Table, or a first ceramics obtained by bonding, with a sintering additive, a first ceramic particle composed of at least one of oxides, carbides, nitrides and carbonitrides selected from the group consisting of metals of Groups4a, 5aand6aof the Periodic Table, Al, Si and Zn. The shell layer3is composed of a second hard sintered body or second ceramics having a different composition from the first hard sintered body. The ratio of the residual free carbon amount Cinin the core material2to the residual free carbon amount Coutin the shell layer3, Cin/Cout, is 0.5 to 2. This prevents shrinkage during the time of sintering and also prevents the strength of the composite construction from lowering due to poor sintering.
