METHOD OF MAKING CUBIC BORON NITRIDE COMPACT

摘要

PROBLEM TO BE SOLVED: To provide an in-situ method of producing a CBN (cubic boron nitride) compact having a layer of refractory material bonded to a surface thereof.

SOLUTION: The method of making the CBN compact having the layer of the refractory material bonded to the surface thereof includes the steps of: producing a reaction mass by placing a mass of CBN particles in contact with a material capable of forming the layer of refractory material; and subjecting the reaction mass to elevated temperature and pressure conditions suitable to form the CBN compact.
