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.

Abstract: A polycrystalline diamond element leaching assembly includes a polycrystalline diamond element, a protective leaching cup surrounding at least a portion of the polycrystalline diamond element, and a protective layer positioned between the polycrystalline diamond element and the protective leaching cup. A method of processing a polycrystalline diamond element includes covering a selected portion of a polycrystalline diamond element with a curable resin layer, curing the curable resin layer to form a protective layer, and exposing at least a portion of the polycrystalline diamond element to a leaching agent. Another method of processing a polycrystalline diamond element includes depositing a curable resin within a protective leaching cup and positioning a polycrystalline diamond element within the protective leaching cup such that the curable resin is displaced so as to surround at least a portion of the polycrystalline diamond element.

Abstract: In an embodiment, a polycrystalline diamond table includes a plurality of bonded diamond grains and a plurality of interstitial regions defined by the plurality of bonded diamond grains. The polycrystalline diamond table may be at least partially leached such that at least a portion of at least one interstitial constituent has been removed from at least a portion of the plurality of interstitial regions by exposure to a leaching agent. The leaching agent may include a mixture having a ratio of weight % hydrofluoric acid to weight % nitric acid of about 1.0 to about 2.4, and water in a concentration of about 50 weight % to about 85 weight %. Various other materials, articles, and methods are also disclosed.

Abstract: In an embodiment, a method of fabricating a leached polycrystalline diamond (“PCD”) body is disclosed. The PCD body includes bonded diamond grains defining interstitial regions at least a portion of which include at least one interstitial constituent disposed therein. The method includes leaching the PCD body with a leaching agent to remove at least a portion of the at least one interstitial constituent therefrom. The leaching agent includes a mixture having hydrofluoric acid in a first concentration of about 10 weight % to about 50 weight %, nitric acid in a second concentration of about 5 weight % to about 25 weight %, and water in a third concentration of about 25 weight % to about 85 weight %. Further embodiments relate to different leaching methods and different leaching agent compositions.

Abstract: A method of processing a polycrystalline diamond material includes exposing at least a portion of a polycrystalline diamond material to a processing agent for processing at least a portion of the polycrystalline diamond material. The method further includes applying a body force to the volume of processing agent while at least the portion of the polycrystalline diamond material is exposed to the processing agent, and heating at least one of the processing agent and at least the portion of the polycrystalline diamond material exposed to the processing agent during application of the body force to the processing agent.
