Sintered body of cubic system boron nitride

Abstract

Abstract PURPOSE: To enhance the chipping and wear resistances of a sintered body by adding carbide, nitride and/or carbonitride of Ti, Zr, Hf, etc., AlN and P 4 C as matrix components to a prescribed amount of cubic system BN in the form of powder and further adding powder of Al, Fe, etc. CONSTITUTION: The titled sintered body is obtd. by sintering 30W70vol% cubic system BN powder having ≤20μm average particle size, 69W15vol% mixed powder and mutual solid soln. powder or mutual compound powder of ≥1 kind of carbide, nitride and/or carbonitride of Ti, Zr, Hf, Ta or Si and powder of AlN, P 4 C or a mixture thereof, and 1W15vol% mixed powder and mutual compound powder of one or more among Al, Fe, Co and Ni. Each particle of the matrix components of the sintered body holds cubic system BN particles firmly and prevents the particles from falling off. COPYRIGHT: (C)1982,JPO&Japio
