Polycrystalline diamond compacts and applications therefor

摘要

Embodiments of the invention relate to polycrystalline diamond compacts (“PDCs”) comprising a polycrystalline diamond (“PCD”) table including a catalyst material therein that has been implanted with ions (e.g., carbon ions) and/or infiltrated from a host material implanted with carbon ions. In an embodiment, a PDC comprises a substrate and a PCD table bonded to the substrate. The PCD table includes a plurality of bonded diamond grains defining a plurality of interstitial regions. The PCD table includes an upper surface from which a region inwardly extends. At least a portion of the interstitial regions of the region includes a catalyst material disposed therein. At least a portion of the catalyst material may be at least saturated with carbon.

1. A polycrystalline diamond compact, comprising:
a substrate; and a polycrystalline diamond table bonded to the substrate, the polycrystalline diamond table including a plurality of bonded diamond grains defining a plurality of interstitial regions, the polycrystalline diamond table including an upper surface from which a region inwardly extends and at least one lateral surface extending about the upper surface, the region further extends laterally from the at least one lateral surface to a distance about equal to a depth to which the region extends from the upper surface, at least a portion of the interstitial regions of the region including a catalyst material disposed therein, at least a portion of the catalyst material being at least saturated with carbon.
