Abstract: A downhole turbine includes a plurality of fins. The plurality of fins have an exit angle that exerts a tangential force on the fin, which imparts a torque on a hub. The fins have an adjustable exit angle that changes in response to changes in the properties of a drilling fluid. The changing exit angle changes the tangential force, which changes the torque on the hub.

Abstract: Embodiments relate to polycrystalline diamond compacts and methods of manufacturing such compacts in which an at least partially leached polycrystalline diamond (“PCD”) table is infiltrated with first and second infiltrants. The first infiltrant includes a low viscosity cobalt-based and/or nickel-based alloy infiltrant. The second infiltrant (e.g., copper) is specifically selected to be more easily infiltrated and/or removed (e.g., leached) than a pure cobalt infiltrant. In an embodiment, a method includes forming a PCD table in the presence of a metal-solvent catalyst in a first high-pressure/high-temperature (“HPHT”) process. The PCD table may be at least partially leached to remove at least a portion of the metal-solvent catalyst therefrom. The leached PCD table and a substrate are subjected to a second HPHT process effective to bond the substrate to the leached PCD table while at least partially infiltrating the PCD table with at least the first and second infiltrants.
