Abstract
Embodiments relate to polycrystalline diamond compacts (“PDCs”), methods of fabricating PDCs, and applications for such PDCs. In an embodiment, a method includes providing an at least partially leached polycrystalline diamond (“PCD”) body. A residual amount of acid may remain in and/or on the at least partially leached PCD body. The method further includes removing and/or neutralizing at least some of the residual amount of acid from the at least partially leached PCD body and/or a substrate to which the at least partially leached PCD body is attached.
