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： This invention is directed to cutting elements having an ultra hard cutting layer such as polycrystalline diamond or polycrystalline cubic boron nitride bonded on a cemented carbide substrate. The interface between the substrate and the cutting layer of each such cutting element is non-planar. The non-planar interface is designed to enhance the operating life of the cutting element by reducing chipping, spalling, partial fracturing, cracking and/or exfoliation of the ultra hard cutting layer, and by reducing the risk of delamination of the cutting layer from the substrate.

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： Thermally stable diamond constructions comprise a diamond body having a plurality of bonded diamond crystals and interstitial regions disposed among the crystals. A metallic substrate is attached to the body. The body includes a first region substantially free of a catalyst material that extends a partial depth from a surface into the body, and a second region that includes the catalyst material. The body can include natural diamond grains and/or a blend of natural and synthetic diamond grains, and is treated to form the first region. Before treatment, a portion of the body to be treated is finished to an approximate final dimension so that the depth of the first region of the finished product is substantially the same as when treated. During treatment, catalyst materials as well as non-catalyst metallic materials are removed from the diamond body to provide a further enhanced degree of thermal stability.

摘要： A non-uniform interface is formed between a polycrystalline ultra hard material layer and a cemented tungsten carbide substrate, or a polycrystalline ultra hard material layer and a transition layer, or a transition layer and a substrate of a cutting element. A first sheet made from an intermediate material is formed and embossed on one face forming a non-uniform pattern raised in relief on the face. The embossed sheet is placed on a face of a presintered substrate. An ultra hard material sheet is formed and embossed, forming a non-uniform face complementary to the non-uniform face on the sheet of intermediate material. The ultra hard material sheet is placed over the intermediate material sheet so that the complementary faces are adjacent to each other. The assembly of substrate and sheets is sintered in a HPHT process. The sintering process causes the first sheet to become integral with the substrate and results in a substrate having a non-uniform cutting face onto which is bonded a polycrystalline ultra hard material layer. Embossed transition material sheets may be employed between the ultra hard material sheet and the first sheet to form transition layers with uniform or non-uniform interfaces.
