1. A polycrystalline diamond compact, comprising:
a substrate; and
a polycrystalline diamond table including a plurality of bonded diamond grains, an interfacial surface bonded to the substrate, and a working surface generally opposing the interfacial surface, the polycrystalline diamond table further including:
a proximal region bonded to the substrate, the proximal region extending from the interfacial surface to an intermediate location within the polycrystalline diamond table, the proximal region including a metallic infiltrant infiltrated into at least some interstitial regions between the bonded diamond grains of the proximal region, the metallic infiltrant exhibiting a surface characteristic of not being chemically etched; and
a distal region extending from the working surface to the intermediate location and being substantially free of the metallic infiltrant, the distal region including at least partially empty interstitial regions between the bonded diamond grains thereof though which at least a portion of the surface of the metallic infiltrant is exposed.
