Abstract

See full text

Embodiments relate to polycrystalline diamond compacts (“PDCs”) including a polycrystalline diamond (“PCD”) table having a diamond grain size distribution selected for improving leachability. In an embodiment, a PDC includes a PCD table bonded to a substrate. The PCD table includes diamond grains exhibiting diamond-to-diamond bonding therebetween. The diamond grains includes a first amount being about 30 to about 65 volume % of the diamond grains and a second amount being about 18 to about 65 volume % of the diamond grains. The first amount exhibits a first average grain size of about 8 μm to about 22 μm. The second amount exhibits a second average grain size that is greater than the first average grain size and is about 15 μm to about 50 μm. Other embodiments are directed methods of forming PDCs, and various applications for such PDCs in rotary drill bits, bearing apparatuses, and wire-drawing dies.
