摘要: Polycrystalline diamond cutting elements with modified catalyst depleted portions and methods of making the same are disclosed herein. A method may include removing inter-bonded diamond grains along an outer surface of a polycrystalline diamond compact to form a frustoconical surface, introducing the polycrystalline diamond compact to a leaching process in which catalyst material that is positioned within interstitial regions between the inter-bonded diamond grains is removed from the polycrystalline diamond compact, and removing inter-bonded diamond grains along the outer surface of the polycrystalline diamond compact to form a polycrystalline diamond cutting element having a peripheral surface.

摘要: 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%.

摘要: A compact, a superabrasive compact and a method of making the compact and superabrasive compact are disclosed. A compact may include a plurality of carbide particles, a binder, and a species. The binder may be dispersed among the plurality of tungsten carbide particles. The species may be dispersed in the compact, wherein the binder has a melting point from about 600° C. to about 1350° C. at ambient pressure. A superabrasive compact may include a diamond table and a substrate. The diamond table may be attached to the substrate. The substrate may have a binder. The melting point of the binder is from about 600° C. to about 1350° C. at high pressure from about 30 kbar to about 100 kbar.
