Abstract
Polycrystalline diamond compacts having parting compound within the interstitial volumes are disclosed herein. In one embodiment, a polycrystalline diamond compact includes a polycrystalline diamond body having a plurality of diamond grains bonded together in diamond-to-diamond bonds, interstitial volumes positioned between the adjacent diamond grains, and a parting compound positioned in at least a portion of the interstitial volumes of the polycrystalline diamond body.
Claims5
A method of making a polycrystalline diamond compact, comprising:
- subjecting a polycrystalline diamond body to a leaching operation in which catalytic material positioned in the interstitial volumes between diamond grains sintered in diamond-to-diamond bonds is removed;
- applying a parting compound to external surfaces of the polycrystalline diamond body and allowing the parting compound to enter the interstitial volumes between the diamond grains, wherein the parting compound is removed from the external surfaces of the polycrystalline diamond body in an abrasive blasting operation;
- and
- removing the parting compound from the external surfaces of the polycrystalline diamond body.
