Abstract:
Polycrystalline diamond compacts (“PDCs”) include a polycrystalline diamond (“PCD”) table in which cobalt is alloyed with phosphorous to improve the thermal stability of the PCD table. For example, a PDC includes a substrate and a PCD table including an upper surface spaced from an interfacial surface that is bonded to the substrate. The PCD table includes a plurality of diamond grains defining a plurality of interstitial regions. The PCD table further includes an alloy comprising at least one Group VIII metal and phosphorous. The alloy is disposed in at least a portion of the plurality of interstitial regions.

Claim (Index 1):
A rotary drill bit, comprising:\n a bit body configured to engage a subterranean formation; and a plurality of polycrystalline diamond cutting elements affixed to the bit body, at least one of the plurality of polycrystalline diamond cutting elements including:\n a substrate; and \n a polycrystalline diamond table including an upper surface spaced from an interfacial surface that is bonded to the substrate, the polycrystalline diamond table including a plurality of diamond grains defining a plurality of interstitial regions, the polycrystalline diamond table further including:\n a first region extending inwardly from at least a portion of the upper surface, the first region including an alloy disposed in at least a portion of the plurality of interstitial regions of the first region, the alloy comprising at least one intermetallic compound including at least one Group VIII metal and phosphorous, wherein the at least one intermetallic compound is present in the alloy in an amount of about 80 weight % to about 100 weight %; and \n a second region adjacent to the substrate, the second region being substantially free of the at least one intermetallic compound.
