Abstract

See full text

Embodiments relate to a polycrystalline diamond compact (“PDC”) including a polycrystalline diamond (“PCD”) table having at least two regions and being bonded to a fine grained cemented tungsten carbide substrate. In an embodiment, a PDC includes a cemented carbide substrate having a cobalt-containing cementing constituent cementing tungsten carbide grains together that exhibit an average grain size of about 1.5 μm or less, and a PCD table having at least one upper region including diamond grains exhibiting an upper average grain size and at least one lower region adjacent to the upper region a lower average grain size that may be at least two times greater than the upper average grain size. The cemented carbide substrate includes an interfacial surface and a depletion zone depleted of the cementing constituent that extends inwardly from the interfacial surface to a depth of, for example, about 30 μm to about 60 μm.
