A high-
hardness Ti(C, N)-based
metal-
ceramic cutter composite is characterized by comprising Ti, TiB2, WC, C, Ni and Mo, wherein the composite is a Ti(C, N)-TiB2-WC
metal-
ceramic cutter material or a Ti(C, N)-TiB2-(W, Ti)C
metal-
ceramic cutter material; Ti is Ti (C5, N5), the
atomic ratio of C to N is 5:5, the average particle size of Ti is 1.5 microns, and the purity is 99.9%;
powder TiB2 is a reinforcement phase, the average particle size is 2 microns, and the purity is 99%; the average particle size of WC is 2 microns, the purity of WC is 99.6%, C is (W0.7, Ti0.3)C, the average particle size of C is 1.5 microns, the purity of C is 99%, and the
mass fraction of WC and C is 15%; Ni is nanometer Ni, the average particle size of Ni is 0.05 micron, and the purity of the Ni is 99.9%; Mo is nanometer Mo, the average purity is 0.06 micron, and the purity is 99%. The high-
hardness Ti(C, N)-based metal-ceramic cutter composite improves the
hardness and the bending strength, at the high temperature, of the Ti(C, N)-based metal-ceramic cutter, improves the mechanical properties of the cutter, saves noble rare metals such as Co, Ta and W, facilitates to improve national resource guarantee and pushes upgrading and updating of hard
alloy materials in China.
