Cermet is an artificial word that designates the combination of a brittle hard phase ('ceramic') with a ductile binder phase ('metal') to form a composite material. In the metal cutting industry cermet is always designated as a TiC- or Ti(C,N)-based composite with an fcc hard phase and a Co-, Ni- or Co/Ni-based binder phase. In the ...

Discussion. The physical and mechanical properties of the Tix Mo 1-x C – Ni binder cermet tiles investigated in this study are summarized in Table 6. The property ranges are typically bounded by as-received at the low end and material in either the stress-relieved or HIP condition at the upper end.

Adjacent to TiC cermet, a continuous Ni-rich layer is found at the interface between the interlayer and TiC cermet substrate. The multilayer granular structure of Ti–Al system and TiC are found in the reaction products. It is noted that void is inevitable in the reaction products and the density is enhanced with the increase of joining pressure.
