摘要
Embodiments relate to methods of fabricating polycrystalline diamond compacts (“PDCs”) in which a removing agent includes at least one supercritical fluid component that is used to remove at least one interstitial constituent from at least a portion of a polycrystalline diamond (“PCD”) body and applications for such PDCs. Removing the at least one interstitial constituent using the removing agent including the at least one supercritical fluid component may provide more rapid and effective removal of the at least one interstitial constituent from a PCD body than conventional acid leaching. In an embodiment, a method of fabricating at least partially porous PCD body includes providing a PCD body in which at least one interstitial constituent is disposed throughout, and removing at least a portion of the at least one interstitial constituent from the PCD body with a removing agent including at least one supercritical fluid component.
