Abstract

PURPOSE: To manufacture a super hard alloy as a base material of a surface coated tool for intermittent cutting by regulating the partial pressures of N and CO in the sintering of powders of WC crystals, a B1 type solid soln. made of carbide, nitride or oxide of a specified metal and an iron group metal as a binder.
CONSTITUTION: In the manufacture of a super hard alloy as a base material of a surface coated tool material for cutting having a hard coated layer of TiC, TiN or the like on the surface, WC crystals, a solid soln. having B1 type crystal structure and consisting of at least one of the IVa, Va and VIa group metals as metallic elements and C, N or C, N and O in an N/(C+N) molar ratio of 0.1W0.5 and an (N+C)/(C+O+N) molar ratio of 0.1W0.5 as nonmetallic elements and an iron group metal such as Co are mixed as starting materials in the form of powders. When the mixture is sintered, the partial pressures of N and CO in the atmosphere are regulated to 10-4W20 Torr during a temp. rise and 10-4W500 Torr during sintering. Thus, a superior base material is obtd.
