摘要： Thermally stable diamond constructions comprise a diamond body having a plurality of bonded diamond crystals and a plurality of interstitial regions disposed among the crystals. A metallic substrate is attached to the diamond body. A working surface is positioned along an outside portion of the diamond body, and the diamond body comprises a first region that is substantially free of a catalyst material, and a second region that includes the catalyst material. The diamond body first region extends from the working surface to depth of at least about 0.02 mm to a depth of less than about 0.09 mm. The diamond body includes diamond crystals having an average diamond grain size of greater than about 0.02 mm, and comprises at least 85 percent by volume diamond based on the total volume of the diamond body.

摘要： A bit body formed of a mixture of matrix material and superabrasive powder and including pockets lined with superabrasive-free matrix material, and a method for forming the same, are provided. The pockets are shaped to receive cutting elements therein. The superabrasive-free matrix material enhances braze strength when a cutting element is brazed to surfaces of the pocket. The method for forming the drill bit body includes providing a mold and displacements. The displacements are coated with a mixture of superabrasive free matrix-material and an organic binder. The mold is packed with a mixture of matrix material and superabrasive powder and the arrangement heated to form a solid drill bit body. When the solid bit body is removed from the mold, pockets are formed by the displacements in the bit body and are lined with the layer of superabrasive-free matrix material. The superabrasive material may be diamond, polycrystalline cubic boron nitride, SiC or TiB2 in exemplary embodiments.

The steel cone includes a plurality of steel cutting elements that each project outwardly a distance therefrom. At least one of the cutting elements comprises a steel base portion that is integral with the cone and that projects a distance therefrom. A cutting element end portion is attached to the base portion and extends therefrom to form a tip of the cutting element. The base and end portions are permanently attached together when the cone and base are in a preexisting rigid state. The cutting element end portion is formed from a wear resistant material having a material microstructure comprising a first phase of grains selected from the group of carbides, borides, nitrides, and carbonitrides of W, Ti, Mo, Nb, V, Hf, Ta, and Cr refractory metals; and a second phase of a binder material selected from the group consisting of Co, Ni, Fe, and alloys thereof.

摘要： Thermally-stable polycrystalline diamond materials of this invention comprise a first phase including a plurality of bonded together diamond crystals, and a second phase including a reaction product formed between a binder/catalyst material and a material reactive with the binder/catalyst material. The reaction product is disposed within interstitial regions of the polycrystalline diamond material that exists between the bonded diamond crystals. The first and second phases are formed during a single high pressure/high temperature process condition. The reaction product has a coefficient of thermal expansion that is relatively closer to that of the bonded together diamond crystals than that of the binder/catalyst material, thereby providing an improved degree of thermal stability to the polycrystalline diamond material.
