摘要： Enhanced inserts are formed having a cylindrical grip and a protrusion extending from the grip. An ultra hard material layer is bonded on top of the protrusion. The inserts are mounted on a rock bit and contact the earth formations off center. The ultra hard material layer is thickest at a critical zone which encompasses a major portion of the region of contact between the insert and the earth formation. Transition layers may also be formed between the ultra hard material layer and the protrusion so as to reduce the residual stresses formed on the interface between the ultra hard material and the protrusion.

摘要： Methods for nondestructively measuring a characteristic within an ultra-hard polycrystalline construction comprises projecting a beam of energy from an emitter onto the construction. The energy is directed to a target region within the ultra-hard polycrystalline construction and passes through the construction where it is received by a detector. The target region can be within a diamond body of the construction, and can relate to an interface between two or more regions within the diamond body. The energy that is received by the detector is evaluated for the purpose of determining the desired measurement characteristic. In an example embodiment, the measured characteristic can be the interface of between two or more regions and the distance from a surface of the construction to the interface. The method can be used to generate an average distance within the construction, and to provide a visual image of the same in a nondestructive manner.

摘要： A cutting element is provided including a substrate having a periphery and an interface surface. An ultra hard material layer is formed over the substrate and interfaces with the interface surface. The interface surface also includes a plurality of spaced apart projections formed inwardly and spaced apart from the periphery and arranged around an annular path, such that each projection includes a convex upper surface defining the projection as viewed in plan view. Each upper surface continuously and smoothly curves in the same direction when viewed along a plane through a diameter of the substrate. Bits incorporating such cutting elements are also provided.

摘要： A polycrystalline diamond layer is bonded to a cemented metal carbide substrate by this process. A layer of dense high shear compaction material including diamond or cubic boron nitride particles is placed adjacent to a metal carbide substrate. The particles of diamond have become rounded instead of angular due to high shear compaction in a multiple roller process. The volatiles in the high shear compaction material are removed and binder decomposed at high temperature, for example, 950.degree. C., leaving residual amorphous carbon or graphite in a layer of ultra hard material particles on the carbide substrate. The substrate and layer assembly is then subjected to a high pressure, high temperature process, thereby sintering the ultra hard particles to each other to form a polycrystalline ultra hard layer bonded to the metal carbide substrate. The layer of high shear compaction material is also characterized by a particle size distribution including larger and smaller particles that are distributed uniformly throughout the layer.
