摘要： A PCD insert comprises a PCD element joined to a cemented carbide substrate at an interface. The PCD element has internal diamond surfaces defining interstices between them. The PCD element comprises a masked or passivated region and an unmasked or unpassivated region, the unmasked or unpassivated region defining a boundary with the substrate, the boundary being the interface. At least some of the internal diamond surfaces of the masked or passivated region contact a mask or passivation medium, and some or all of the interstices of the masked or passivated region and of the unmasked or unpassivated region are at least partially filled with an infiltrant material.

摘要： An earth-boring bit has a bit body, at least one cantilevered bearing shaft, including a base and a cylindrical journal bearing surface extending inwardly and downwardly from the bit body, and at least one cutter mounted for rotation on the cylindrical journal bearing surface of the bearing shaft. A seal assembly is disposed between the cylindrical journal bearing surface and the cutter proximally to the base of the cantilevered bearing shaft. The seal assembly includes at least one rigid seal ring having a seal face in contact with a second seal face. At least one of the seal faces is at least partially formed of a super-hard material having wear-resistance greater than, and a coefficient of sliding friction less than, that of the rigid seal ring material.

摘要： An earth boring bit is shown having a bit body and at least one cutter rotatably secured to the bit body. The cutter has a plurality of teeth formed integrally thereon and arranged in circumferential rows. Each of the teeth includes an outer end, an inner end, a pair of flanks and a crest which transversely connects the ends and flanks. During the manufacturing process, a temporary protective coating is applied at a region of the tooth root which comprises a sharp corner at the intersection of the flanks and ends in order to prevent a carburized case from forming in that region during subsequent carburization of the cutter. The cutter is then carburized, heat treated and mounted on a bit body.

摘要： An earth-boring bit has a bit body and a cantilevered bearing shaft depending from the bit body. The cutter is mounted for rotation on the bearing shaft. Cutting elements are secured within holes formed in the cutter. At least some of the cutting elements include a body of hard metal which has a cylindrical base inserted in an interference fit within one of the holes. The body has a contact surface on its cutting end. A layer of super-hard material is bonded to the contact surface to provide a tip for the cutting end. The layer may be formed of a free-standing film of diamond which is brazed to the contact surface. It may also be formed with a high temperature, high pressure process directly onto the body of tungsten carbide.
