摘要： A rotary cone bit, having a functionally-engineered surface of this invention, comprises a bit body having at least one leg extending therefrom, and a cone that is rotatably disposed on the leg. The cone typically comprises a plurality of cutting elements that project outwardly therefrom. The cutting elements comprises a cermet material selected from the group consisting of refractory metal carbides, nitrides, borides, carbonitrides and mixtures thereof. A functionally-engineered material is disposed over a surface portion of at least one of the cutting elements to form a wear resistant surface thereon. The wear resistant surface has a hardness that is different than that of the underlying cutting element. The wear resistant surface is provided by forming a conformable material mixture by combining one or more powders selected from the group consisting of cermets, carbides, borides, nitrides, carbonitrides, refractory metals, Co, Fe, Ni, and combinations thereof, with an applying agent. The applied material mixture is pressurized under conditions of elevated temperature to consolidate and sinter the material mixture, thereby forming the wear resistant surface. The material mixture is consolidated and sintered in a manner that avoids unwanted material migration between the applied material mixture and substrate, thereby providing a fully-densified wear surface having desired properties of hardness and/or fracture toughness.

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.

摘要： Ordered elastomeric composites comprise an ordered arrangement of a number of first elastomeric phases distributed uniformly within a continuous matrix second elastomeric phase. The second phase can be formed from an elastomeric material that is relatively harder than an elastomeric material that is used to form the first phases. Each first phase can be in the form of a core having a defined length and diameter, and the second phase can be formed from a number of shells that each surround a respective core. In a preferred embodiment, the arrangement of cores and shells are aligned coaxially with one another to provide a cellular structure. Ordered elastomeric composites of this invention can be used to form part of or an entire elastomeric seal, e.g., in the form of an annular ring adapted for use in a rotary cone drill bit.

摘要： A high performance rock bit journal seal is formed from a composite material comprising an elastomeric material and a nonelastomeric polymeric material. The polymeric material is preferably in the form of fibers compiled or woven into a sheet. The elastomeric material may include one or more lubricant additives. The composite seal material comprises a number of repeating sheets of polymeric fabric that are bonded together with the elastomeric material. The seal can either be formed entirely of the composite seal material or partially of the composite material, in which case it is preferred that the seal wear or dynamic surface be formed from the composite material and the remaining portion of the seal be formed from an elastomeric material. The seal can be used as a primary journal seal, or as a secondary journal seal in a dual seal bit. Seals formed from the composite seal material display enhanced wear resistance, reduced coefficient of friction, and improved high-temperature stability and endurance when compared to noncomposite seal materials, thereby both extending the useful life of seals formed therefrom formed and of rock bits that employ such seals.
