摘要： A device, system and method for nondestructively obtaining qualitative and/or quantitative information relating to the material properties of a region in a diamond body comprises directing x-rays onto the body. The body can comprise sintered or unsintered diamond. The body can ultimately be in the form of a cutting element used with a subterranean drill bit. The x-rays penetrate the body and cause a target element within the desired region including the same to emit x-ray fluorescence. The emitted x-ray fluorescence is received and information relating to content, location, and/or distribution of the target element in the region within the body is determined therefrom. The measured region can extend axially or radially from a surface of the body, and the target elements are nondiamond materials that can be constituents of a substrate attached to the body, or of a container used during HPHT sintering of the body.

摘要： Thermally stable diamond constructions comprise a diamond body having a plurality of bonded diamond crystals, a plurality of interstitial regions disposed among the crystals, and a substrate attached to the body. The body includes a working surface and a side surface extending away from the working surface to the substrate. The body comprises a first region adjacent the side surface that is substantially free of a catalyst material and that extends a partial depth into the diamond body. The first region can further extend to at least a portion of the working surface and a partial depth therefrom into the diamond body. The diamond body can be formed from natural diamond grains and/or a mixture of natural and synthetic diamond grains. A surface of the diamond body is treated to provide the first region, and before treatment is finished to an approximate final dimension.

摘要： A cutting element is provided, including a substrate and an ultra-hard material layer formed over the substrate. At one end of the substrate is an interface surface that interfaces with the ultra-hard material layer to bond the layer to the substrate. The interface surface includes a first or outer annular section that extends to the peripheral edge of the substrate, and a second or inner section that is radially inside the first section. The interface surface includes several spaced-apart projections arranged in an annular row. In one aspect, each projection has an upper surface that defines a groove bisecting the projection. In another aspect, the interface surface may include a bridge coupling adjacent projections.

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： 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.
