Abstract

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.
