Abstract: A compact comprising substantially graphite-free diamond particles having a continuous coating of titanium or molybdenum held in a matrix into which the titanium or molybdenum can diffuse. The matrix may for example, be an alloy selected from the group of Fe/Ni, Ni/Co/Cr/Fe, Fe/Si and Ti/Si alloys. The invention also provides a method of making such a compact by mixing the desired metal powders in suitable proportions with the coated diamond particles and compacting the mixture under pressure and temperature conditions in the diamond stable zone.

Abstract: Grains of superabrasive material may be infiltrated with a molten metal alloy at a relatively low temperature, and the molten metal alloy may be solidified within interstitial spaces between the grains of superabrasive material to form a solid metal alloy having the grains of superabrasive material embedded therein. The solid metal alloy with the grains of superabrasive material embedded therein may be subjected to a high pressure and high temperature process to form a polycrystalline superabrasive material. A polycrystalline superabrasive material also may be formed by depositing material on surfaces of grains of superabrasive material in a chemical vapor infiltration process to form a porous body, which then may be subjected to a high pressure and high temperature process. Polycrystalline compacts and cutting elements including such compacts may be formed using such methods.

Abstract: A polycrystalline superhard construction comprises a body of polycrystalline superhard material, and a substrate of hard material bonded thereto along an interface. The body of polycrystalline superhard material comprises a first region abutting the substrate along the interface and a second region bonded to the first region. The second region defines a rake face, a cutting edge, a chamfer and at least a part of a flank face, the cutting edge being defined by an edge of the flank face joined to the chamfer, the chamfer extending between the cutting edge and the rake face. The height of the chamfer in a plane parallel to the plane through which the longitudinal axis of the polycrystalline superhard construction extends is less than the thickness of the second region.

Abstract: Polycrystalline diamond compacts (“PDCs”) and methods of manufacturing such PDCs. In an embodiment, the PDC includes a polycrystalline diamond (“PCD”) table having at least a portion of a metal-solvent catalyst removed therefrom. Removing at least a portion of a metal-solvent catalyst from the PCD table may increase the porosity of the PCD table relative to a PCD table that has not been treated to remove the metal-solvent catalyst. Likewise, removing at least a portion of a metal-solvent catalyst from the PCD table may decrease the specific magnetic saturation and increase the coercivity of the PCD table relative to a PCD table that has not been treated to remove the metal-solvent catalyst.
