Abstract: Embodiments relate to polycrystalline diamond compacts (“PDCs”) that are less susceptible to liquid metal embrittlement damage due to the use of at least one transition layer between a polycrystalline diamond (“PCD”) layer and a substrate. In an embodiment, a PDC includes a PCD layer, a cemented carbide substrate, and at least one transition layer bonded to the substrate and the PCD layer. The at least one transition layer is formulated with a coefficient of thermal expansion (“CTE”) that is less than a CTE of the substrate and greater than a CTE of the PCD layer. At least a portion of the PCD layer includes diamond grains defining interstitial regions and a metal-solvent catalyst occupying at least a portion of the interstitial regions. The diamond grains and the catalyst collectively exhibit a coercivity of about 115 Oersteds or more and a specific magnetic saturation of about 15 Gauss·cm3/grams or less.

Abstract: A method of processing a polycrystalline diamond element includes forming a protective layer over a selected portion of a polycrystalline diamond element, the polycrystalline diamond element having a polycrystalline diamond table that includes a superabrasive face, a superabrasive side surface, and a chamfer extending between the superabrasive face and the superabrasive side surface. A portion of the superabrasive side surface is covered by the protective layer and the protective layer is not formed over the chamfer. The method includes exposing at least a portion of the polycrystalline diamond element to a leaching solution. A polycrystalline diamond element has a polycrystalline diamond table that includes a leached volume extending from the superabrasive face to a portion of the chamfer proximate to the superabrasive side surface, and the leached volume does not substantially extend along the superabrasive side surface.

Abstract: In an embodiment, a method of fabricating a polycrystalline diamond compact is disclosed. The method includes sintering a plurality of diamond particles in the presence of a metal-solvent catalyst to form a polycrystalline diamond body; leaching the polycrystalline diamond body to at least partially remove the metal-solvent catalyst therefrom, thereby forming an at least partially leached polycrystalline diamond body; and subjecting an assembly of the at least partially leached polycrystalline diamond body and a cemented carbide substrate to a high-pressure/high-temperature process at a pressure to infiltrate the at least partially leached polycrystalline diamond body with an infiltrant. The pressure of the high-pressure/high-temperature process is less than that employed in the act of sintering of the plurality of diamond particles.

Abstract: A superabrasive compact (e.g., a polycrystalline diamond compact) including a substrate and at least one feature for reducing the susceptibility of the substrate to liquid metal embrittlement during brazing operations is disclosed. The superabrasive compact may include a region between the substrate and a superabrasive table in which residual tensile stresses are located. The at least one feature may reduce the susceptibility of the substrate to liquid metal embrittlement by altering the stress state and/or substantially preventing the substrate from being wetted at the residual stress region.
