Performance of TiC base cermets sintered by different techniques

The performance and structure of some advanced TiC base cermets with Ni steel binder, sintered by different techniques (sintering atmosphere, vacuum level, etc.), prospective for metal forming, were investigated. It is shown that the influence of sintering technology on the performance characteristics of TiC cermets (strength, wear resistance) depends on the composition and structure of their binder. Regarding the performance characteristics (transverse rupture strength and adhesive wear resistance) TiC base cermets with martensitic-bainitic steel binder sintered by optimum techniques demonstrated a marked superiority over those with austenitic binder and particularly over those with Ni alloy.
