Claims20
A method of forming an abrasive element, comprising:
- sintering a powder mixture including a plurality of superabrasive particles, a plurality of sp2-carbon-containing particles, and a metallic constituent to form the abrasive element;
- and
- wherein the plurality of sp2-carbon-containing particles are present in the powder mixture in an amount greater than zero weight percent to about 5 weight percent of the powder mixture.
A method of forming a superabrasive element, comprising:
- sintering a powder mixture including a plurality of diamond particles, a plurality of sp2-carbon-containing particles, a plurality of carbide particles, and a metallic constituent to form the superabrasive element;
- wherein the plurality of sp2-carbon-containing particles are present in the powder mixture in an amount greater than zero weight percent to about 45 weight percent of the powdered mixture.
