Abstract
Embodiments of the invention relate to methods of fabricating polycrystalline diamond compacts (“PDCs”) and applications for such PDCs. In an embodiment, a method of fabricating a PDC includes providing a polycrystalline diamond (“PCD”) table in which a catalyst is disposed throughout, leaching the PCD table with a gaseous leaching agent to remove catalyst from the PCD table and bonding the at least partially leached PCD table to a substrate to form a PDC.
