Abstract: 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.

Abstract: Thermally-stable polycrystalline diamond materials 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.

Abstract: An improved braze alloy is microalloyed to include about 0.0005 wt % to about 0.5 wt % of at least one aggressively surface acting element selected from tellurium (Te), selenium (Se), antimony (Sb), bismuth (Bi), and gallium (Ga), or any combination thereof. The braze alloys may include at least about 30% by weight of at least one base metal selected from the group of silver (Ag), copper (Cu), gold (Au), nickel (Ni), or aluminum (Al). In one example, a silver braze alloy suitable for brazing a cutter to a drill bit body is microalloyed to improve a characteristic of the braze material.
