A superabrasive compact and a method of making the superabrasive compact are disclosed. A superabrasive compact may comprise a superabrasive volume and a substrate. The substrate may be attached to the superabrasive volume via an interface. The superabrasive volume may be formed by a plurality of polycrystalline superabrasive particles. The superabrasive particles may have nano or sub-micron scale surface texture.The surface texture is the result of treating the diamond or cBN particles in hydrogen or oxygen- containing atmoshere. The diamond or cBN particles are joined with the cemented tungsten carbide substrate by high pressure high temperature sintering.


Polycrystalline diamond cutters for rotary drill bits and methods of making the same are disclosed. A polycrystalline diamond compact includes a polycrystalline diamond body having a working surface, an interface surface, and a perimeter surface. The polycrystalline diamond compact also includes a substrate bonded to the polycrystalline diamond body along the interface surface. A non-diamond volume fraction of the polycrystalline diamond body is greater at the interface surface than at the working surface.

A superabrasive compact and a method of making the superabrasive compact are disclosed. A method of making a superabrasive compact may comprise steps of treating a substrate to remove a first binder material from a portion of the substrate; introducing a first material into the portion of the substrate, forming a first modified substrate; and treating the porting of modified substrate to remove at least a part of the first material to form a second modified substrate.


A method for making a polycrystalline diamond compact including the step of providing a polycrystalline diamond compact. The compact has a substrate of a hard metal composition of material and a volume of diamond material disposed on the substrate. The diamond material includes a mixture of diamond particles and a binder-catalyst. At least one pre-coating layer of organic material impermeable to a given acid or mixture of given acids is applied to at least an exterior surface of the substrate. At least one layer of primer material that is impermeable to a given acid or mixture of given acids is applied on the at least one pre-coating layer. A layer of top coating material that is impermeable to the given acid or mixture of given acids is applied to the at least one primer layer. When the given acid or mixture of given acids is applied to the compact to leach the binder-catalyst from the diamond material the at least one pre-coating layer, at least one primer layer and layer of top coating material protect the coated portions of the compact.


A cutter assembly includes a substrate and at least one island. The substrate includes a surface circumscribed by a peripheral edge, a flank surface extending from the peripheral edge, and at least one pocket with an opening on the surface and spaced apart from the peripheral edge. The at least one pocket extends from the opening towards an interior of the substrate. The at least one island is in the at least one pocket, and the at least one island includes a cutting surface that is exposed by the opening of the at least one pocket.


Diamond bodies and methods of manufacture are disclosed. Diamond bodies are formed from at least a bimodal, alternatively a tri-modal or higher modal, feedstock having at least one fraction of modified diamond particles with a fine particle size (0.5-3.0 m) and at least one fraction of diamond particles with coarse particle size (15.0 to 30 m). During high pressurehigh temperature processing, fine particle sized, modified diamond particles in the first fraction preferentially fracture to smaller sizes while preserving the morphology of coarse particle sized diamond particles in the second fraction. Diamond bodies incorporating the two fractions have a microstructure including second fraction diamond particles dispersed in a continuous matrix of first fraction modified diamond particles and exhibit improved wear characteristics, particularly for wear associated with drilling of geological formations.
