POLYCRYSTALLINE DIAMOND COMPACTS, RELATED PRODUCTS, AND METHODS OF MANUFACTURE |
摘要 |
Embodiments relate to polycrystalline diamond compacts ("PDCs") and methods of manufacturing such PDCs in which an at least partially leached polycrystalline diamond ("PCD") table is infiltrated with a low viscosity cobalt-based alloy 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 method includes at least partially leaching the PCD table to remove at least a portion of the metal-solvent catalyst therefrom to form an at least partially leached PCD table. The method includes subjecting the at least partially leached PCD table and a substrate to a second HPHT process effective to at least partially infiltrate the at least partially leached PCD table with an alloy infiltrant comprising at least one of a cobalt-based or nickel based alloy infiltrant having a composition at or near a eutectic composition of the alloy infiltrant. |
