Abstract: Polycrystalline diamond cutters for rotary drill bits and methods of making the same are disclosed. Polycrystalline diamond cutters include a support substrate and a polycrystalline diamond body coupled to the support substrate. The polycrystalline diamond body includes a plurality of diamond grains exhibiting inter-diamond bonding therebetween and defining a plurality of interstitial regions, a non-catalytic material distributed throughout the polycrystalline diamond body in a detectable amount, and a catalytic material distributed throughout the polycrystalline diamond body in a detectable amount.

Abstract: A superabrasive cutter and a method of making the superabrasive cutter are disclosed. The superabrasive cutter may comprise a plurality of polycrystalline superabrasive particles and about 0.01% to about 4% by weight of the superabrasive particles of a dopant as evaluated prior to a high pressure/high temperature process. The dopant may be immiscible with a catalyst for forming the polycrystalline superabrasive particles.

Abstract: Cutting elements having accelerated leaching rates and methods of making the same are disclosed herein. In one embodiment, a method of forming a cutting element includes assembling a reaction cell having diamond particles, a non-catalyst material, a catalyst material, and a substrate within a refractory metal container, where the non-catalyst material is generally immiscible in the catalyst material at a sintering temperature and pressure. The method also includes subjecting the reaction cell and its contents to a high pressure high temperature sintering process to form a polycrystalline diamond body that is attached to the substrate. The method further includes contacting at least a portion of the polycrystalline diamond body with a leaching agent to remove catalyst material and non-catalyst material from the diamond body, where a leaching rate of the catalyst material and the non-catalyst material exceeds a conventional leaching rate profile by at least about 30%.

Abstract: 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.
