摘要： A polycrystalline-diamond cutting element for a drill bit of a downhole tool. The cutting element includes a substrate and a diamond table bonded to the substrate. The diamond table includes a diamond filler with at least one leached polycrystalline diamond segment packed therein along at least one working surface thereof. The cutting element may be formed by positioning the diamond table on the substrate and bonding the diamond table onto the substrate such that the polycrystalline diamond segment is positioned along at least one working surface of the diamond table. A spark plasma sintering or double press operation may be used to bond the diamond table onto the substrate.

摘要： A turbine matrix sleeve in accordance with the invention includes an inner cylindrical structure made up of a first material. The inner cylindrical structure may include multiple blades and multiple channels running between the blades along an outside diameter thereof. The inner cylindrical structure further includes threads, such as right-hand or left-hand threads, on an outer surface thereof. An outer layer, made up of a second material different from the first material, is integrally bonded to the threads. This outer layer may be optionally embedded with hardened inserts or buttons, such as PDC inserts, diamond inserts, TSP inserts, or the like. The threaded surface on the inner cylindrical structure significantly improves the bond between the outer layer and the inner cylindrical structure and creates a mechanical lock therebetween.

摘要： A progressive cavity type motor or pump including a stator insert with a reinforcing agent dispersed in a manner to improve properties of the stator insert. The reinforcing agent may be a fiber, nanotube, metal, ceramic, or polymer. A dispersing agent may be used to obtain a homogenous distribution. A magnetic reinforcing agent may be incorporated into a stator insert. The stator insert is subjected to a magnetic field to orient the magnetic reinforcing agent in a particular orientation. The magnetic field may also reposition the magnetic reinforcing agent within the stator insert. The stator insert may be formed by injection molding, transfer, or compression molding among other methods.

摘要： Methods of forming a new wear and abrasion overlay formed with the steel surfaces of components for earth boring bits, and the components formed by the methods are disclosed. The overlay comprises a hard material particulate containing a metal carbide and an alloy steel matrix. The volume fraction of the hard material particulate in the overlay is greater than about 75%, the average particle size of the hard material particulate is between about 40 mesh and about 80 mesh, and the thickness of the overlay is less than about 0.050 inches. The process of manufacture includes the steps of fixing a monolayer of hard material particulate to the surface of a flexible mold, filling the mold with materials and powders, and CIP densifying to form a preform. The preform is then forged to near 100% density in a rapid solid state densification powder metallurgy process. The resulting bit component has an integrally formed overlay with superior physical properties.
