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.

Polycrystalline diamond compact

Method of processing a polycrystalline diamond element may include laser ablating at least a portion of a polycrystalline diamond element to form a laser-shaped surface and exposing at least a portion of the laser-shaped surface to a leaching solution to define a leached polycrystalline diamond volume and an unleached polycrystalline diamond volume.

Leached diamond elements and leaching systems, methods and assemblies for processing diamond elements

Embodiments of the invention relate to methods of making articles having portions of polycrystalline diamond bonded to a surface of a substrate and polycrystalline diamond compacts made using the same. In an embodiment, a molding technique is disclosed for forming cutting tools comprising polycrystalline diamond portions bonded to the outer surface of a substrate.

Methods of making a polycrystalline diamond structure

Embodiments disclosed herein are directed to a superabrasive compact including one or more superabrasive cutting portions or segments, rotary drill bits including one or more superabrasive compacts, and related methods (e.g., methods of fabricating and/or operating the superabrasive compacts). For example, the superabrasive compact may include polycrystalline diamond that may form at least a portion of a working surface of the superabrasive compact.

Multi-part superabrasive compacts, rotary drill bits including multi-part superabrasive compacts, and related methods

A polycrystalline diamond element includes a polycrystalline diamond table having a body of bonded diamond particles with interstitial regions. A first volume of the body includes an interstitial material and a second volume of the body has a lower concentration of interstitial material within the interstitial regions than the first volume. The polycrystalline diamond element includes an element face and a peripheral surface. The first volume is adjacent to a central portion of the element face and the second volume is adjacent to the peripheral surface. A method of processing a polycrystalline diamond element includes forming a concave region in the polycrystalline diamond element, exposing at least a portion of the concave region to a leaching solution, and removing at least a portion of the polycrystalline diamond element that was exposed to the leaching solution from the polycrystalline diamond element.

Leached superabrasive elements and leaching systems, methods and assemblies for processing superabrasive elements

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.

Superabrasive elements and methods for processing and manufacturing the same using protective layers

Embodiments of the invention are directed to cutting tool assemblies, material-removing machines that include cutting tool assemblies, and methods of use and operation thereof. In some embodiments, the cutting tool assemblies described herein may be used in material-removing machines that may remove target material. For example, the cutting tool assemblies may include one or more superhard working surfaces and/or one or more shields.

Cutting tool assemblies including superhard working surfaces, material-removing machines including cutting tool assemblies, and methods of use

Embodiments relate to polycrystalline diamond compacts ('PDCs') including a substrate and a polycrystalline diamond ('PCD') table mounted to the substrate. The PCD table includes an upper surface and one or more recesses extending inwardly from the upper surface of the PCD table. The one or more recesses may help prevent, stop, or limit crack propagation and may redistribute, breakup, or relieve stresses in the PCD table. In some embodiments, the one or more recesses exhibit, in plain view, a generally rectangular geometry, a generally circular geometry, or a generally triangular geometry. In some embodiments, the PCD table includes one or more channels that extend from a vertex of the one or more recesses. In some embodiments, the one or more channels and the one or more recesses may be at least partially filled with a sacrificial material. Methods for forming such PDCs are also discussed.

Methods of forming polycrystalline diamond compact including crack-resistant polycrystalline diamond table

A polycrystalline diamond element includes a polycrystalline diamond table having a body of bonded diamond particles with interstitial regions. A first volume of the body includes an interstitial material and a second volume of the body has a lower concentration of interstitial material within the interstitial regions than the first volume. The polycrystalline diamond element includes an element face and a peripheral surface. The first volume is adjacent to a central portion of the element face and the second volume is adjacent to the peripheral surface. A method of processing a polycrystalline diamond element includes forming a concave region in the polycrystalline diamond element, exposing at least a portion of the concave region to a leaching solution, and removing at least a portion of the polycrystalline diamond material that was exposed to the leaching solution from the polycrystalline diamond element.

Leached superabrasive elements and leaching systems methods and assemblies for processing superabrasive elements

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 (&#x201c;CTE&#x201d;) 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&#xb7;cm/grams or less.
