Abstract
In an embodiment, a polycrystalline diamond compact includes a polycrystalline diamond table having nanocrystalline diamond present in an amount greater than zero weight percent to about 5 weight percent of the polycrystalline diamond table. The polycrystalline diamond table including a catalyst material distributed throughout at least a portion thereof. The polycrystalline diamond compact includes a substrate bonded to the polycrystalline diamond table.
Claims25
A polycrystalline diamond compact, comprising:
- a polycrystalline diamond table including nanocrystalline diamond present in an amount greater than zero weight percent to about 5 weight percent of the polycrystalline diamond table, the polycrystalline diamond table including a catalyst material distributed throughout at least a portion thereof;
- and
- a substrate bonded to the polycrystalline diamond table.
A polycrystalline diamond compact, comprising:
- a polycrystalline diamond body including nanocrystalline diamond present in an amount greater than zero weight percent to about 5 weight percent of the polycrystalline diamond body, the polycrystalline diamond body including a catalyst material distributed throughout at least a portion thereof.
A polycrystalline diamond compact, comprising:
- a polycrystalline diamond body including a catalyst material distributed throughout at least a portion thereof, the polycrystalline diamond body fabricated according to a process comprising:
- mixing a plurality of sp2-carbon-containing particles and a plurality of diamond particles to form a mixture;
- and
- sintering the mixture in the presence of the catalyst material to form the polycrystalline diamond body;
- wherein the plurality of sp2-carbon-containing particles was present in the mixture in an effective amount such that the polycrystalline diamond body is capable of cutting a distance of at least 1868 linear feet in a granite workpiece during a vertical turret lathe thermal stability test without removal of the catalyst material from the polycrystalline diamond body.
