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: 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: Methods of making superabrasive elements may include forming a first superabrasive body, forming discrete components from the first superabrasive body, and then forming a second abrasive element from the discrete components. For example, microstructures (e.g., micro-cylinders or other geometries) may be formed from the first superabrasive element, catalyst materials may be removed from the microstructures, with the microstructures being recombined and bonded during a subsequent high-pressure, high-temperature (HPHT) process. In other embodiments, superabrasive elements may be formed to include microfeatures formed in a surface of a superabrasive body or table. For example, blind holes or slots may be formed in a surface of the element for use in attaching the superabrasive table to a substrate. The holes may be coated to provide an impermeable surface, or they may be filled with a metallic material to enhance the attachment to a substrate.

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.
