The plurality of particles may be included within the superabrasive crystal. The plurality of particles may comprise a non-catalyst material.
Claims21
A superabrasive material comprising:
- a cubic boron nitride (cBN) grain having a single crystal structure;
- and
- a plurality of particles included within the cBN grain, wherein the plurality of particles comprise a non-catalyst material.
A method, comprising:
- providing a plurality of hexagonal boron nitride (hBN) grains;
- providing a catalyst and a plurality of particles as non-binder materials;
- and
- subjecting the plurality of hBN grains, the catalyst, and non-binder material to a high pressure and high temperature for a time period sufficient to form a single crystal structure of a cubic boron nitride (cBN) grain, wherein the plurality of particles are dispersed within the single crystal structure of the cBN grains.
