摘要： Cutting elements include a volume of superabrasive material. The volume of superabrasive material comprises a front-cutting surface, an end-cutting surface, a cutting edge, and lateral side surfaces extending between and intersecting each of the front-cutting surface and the end-cutting surface. An earth-boring tool may comprise a bit body and at least one cutting element attached to the bit body. Methods of forming cutting elements comprise forming a volume of superabrasive material comprising forming a front-cutting surface, an end-cutting surface, a cutting edge, and lateral side surfaces extending between and intersecting each of the front-cutting surface and the end-cutting surface. Methods of forming earth-boring tools comprise forming a cutting element and attaching the cutting element to an earth-boring tool.

摘要： A layer of matrix powder is deposited within a mold opening. A layer of super-abrasive particles is then deposited over the matrix powder layer. The super-abrasive particles have a non-random distribution, such as being positioned at locations set by a regular and repeating distribution pattern. A layer of matrix powder is then deposited over the super-abrasive particles. The particle and matrix powder layer deposition process steps are repeated to produce a cell having alternating layers of matrix powder and non-randomly distributed super-abrasive particles. The cell is then fused, for example using an infiltration, hot isostatic pressing or sintering process, to produce an impregnated structure. A working surface of the impregnated structure that is oriented non-parallel (and, in particular, perpendicular) to the super-abrasive particle layers is used as an abrading surface for a tool.

摘要： A chromium-free, distributed hardfacing disposable on a surface of a wellsite component is disclosed. The hardfacing includes a metal filler (e.g., nickel) and particles distributed about the filler. The particles include pellets made of tungsten carbide and pieces made of angular molybdenum carbide. The pieces are smaller than the pellets for distribution in the filler between the pellets whereby a uniform distribution of particles is provided about the filler.

摘要： Methods of forming at least a portion of an earth-boring tool include providing particulate matter including a hard material in a mold cavity, melting a metal and the hard material to form a molten composition comprising a eutectic or near-eutectic composition of the metal and the hard material, casting the molten composition to form the at least a portion of an earth-boring tool within the mold cavity, and providing an inoculant within the mold cavity. Methods of forming a roller cone of an earth-boring rotary drill bit include forming a molten composition, casting the molten composition within a mold cavity, solidifying the molten composition to form the roller cone, and controlling grain growth using an inoculant as the molten composition solidifies. Articles including components of earth-boring tools are fabricated using such methods.

The volume of superabrasive material includes a cutting face having at least one recess extending into the volume of superabrasive material and/or at least one protrusion extending outward from the volume of superabrasive material. The volume of superabrasive material includes a first chamfer surface having a peripheral edge and a radially innermost edge. The peripheral edge of the first chamfer surface is located proximate a cutting edge of the volume of superabrasive material. A radial width of the first chamfer surface is between about 0.002 inch and about 0.045 inch. The volume of superabrasive material also includes a second chamfer surface having a peripheral edge and a radially innermost edge. The peripheral edge of the second chamfer surface is located adjacent the radially innermost edge of the first chamfer surface.

摘要： A low surface friction body for a drill bit includes a matrix drill bit body. The body includes a particulate phase having a friction-reducing additive, and a binding material that bonds the particulate phase using a suitable manufacturing process such as selective laser sintering. The particulate phase may include tungsten carbide, the friction-reducing additive may be polytetrafluoroethylene, and the binder material may be copper or cobalt. The friction-reducing additive is distributed throughout at least a portion of the drill bit body that includes the surface that will come into contact with drill cuttings and drilling fluid during operation. The molecular properties of the friction-reducing additive result in a drill bit body having a surface that is resistant to sticking even after enduring chipping and other types of wear.

摘要： Embodiments relate to polycrystalline diamond compacts (“PDCs”) and methods of manufacturing such PDCs in which an at least partially leached polycrystalline diamond (“PCD”) table is infiltrated with a low viscosity cobalt-based alloy infiltrant. In an embodiment, a method includes forming a PCD table in the presence of a metal-solvent catalyst in a first high-pressure/high-temperature (“HPHT”) process. The method includes at least partially leaching the PCD table to remove at least a portion of the metal-solvent catalyst therefrom to form an at least partially leached PCD table. The method includes subjecting the at least partially leached PCD table and a substrate to a second HPHT process effective to at least partially infiltrate the at least partially leached PCD table with an alloy infiltrant comprising at least one of a cobalt-based or nickel based alloy infiltrant having a composition at or near a eutectic composition of the alloy infiltrant.
