Abstract
A superabrasive compact and a method of making the superabrasive compact are disclosed. A method of making a superabrasive compact comprises steps of providing a plurality of superabrasive particles having a particle size distribution with a first ratio (d50)/(d50 principle particles) ranging from about 0.86 to about 0.92; providing a support to the plurality of superabrasive particles; and subjecting the support and the plurality of superabrasive particles to conditions of an elevated temperature and pressure suitable for producing the polycrystalline superabrasive compact.
Claims8
A method of making a superabrasive compact, comprising:
- providing a plurality of superabrasive particles having a broad fine particle size distribution with a mean particle size d50 ranging from about 12 microns to about 30 microns and having a tail of fine superabrasive particles ranging from about 1 micron to about 9 microns;
- providing a support to the plurality of superabrasive particles;
- and
- subjecting the support and the plurality of superabrasive particles to conditions of an elevated temperature and pressure suitable for producing the polycrystalline superabrasive compact,
- wherein the particle size distribution has a first metric (d50)/(d50 principle particles), wherein the first metric is from about 0.86 to about 0.92.
