Abstract

PURPOSE:To improve the plastic deformation resistance and impact resistance of the titled cutting tip by incorporating the specific amounts of NbC and ZrC as the hard phase components into the cutting tip made of ultra hard cermet obtd. by sintering TiC, TiN, TaC and WC as the hard phase components and W and Ni, Co, etc., as the binder phase components. CONSTITUTION:1-25wt.% NbC and 0.1-5% ZrC as the hard phase components are incorporated into the cutting tip made of cermet by a sintered alloy having the compsn. contg., by weight, 10-40% TiN, 3-30% TaC, 5-25% WC and the balance TiC as the hard phase components and contg. 2-15% W and one or two kinds between 5-25% Ni and Co as the binder phase components at the time of sintering. The cutting tip having excellent plastic deformation resistance and impact resistance of cermet, having high hardness and furthermore having excellent loss resistance and wear resistance in the use can be produced.
