摘要： Polycrystalline diamond constructions include a diamond body comprising a matrix phase of bonded together diamond crystals formed at high pressure/high temperature conditions with a catalyst material. The sintered body is treated remove the catalyst material disposed within interstitial regions, rendering it substantially free of the catalyst material used to initially sinter the body. Accelerating techniques can be used to remove the catalyst material. The body includes an infiltrant material disposed within interstitial regions in a first region of the construction. The body includes a second region adjacent the working surface and that is substantially free of the infiltrant material. The infiltrant material can be a Group VIII material not used to initially sinter the diamond body. A metallic substrate is attached to the diamond body, and can be the same or different from a substrate used as a source of the catalyst material used to initially sinter the diamond body.

摘要： Thermally stable ultra-hard compact constructions comprise a polycrystalline diamond body substantially free of a catalyst material, and a substrate that is joined thereto. The substrate can be ceramic, metallic, cermet and combinations thereof, and can be joined to the body by a braze material or other material that forms an attachment bond at high pressure/high temperature conditions. The body and substrate are specially formed having complementary interfacing surface features to facilitate providing an improved degree of attachment therebetween. The complementary surface features can in the form of openings and projections, e.g., one of the body or substrate can comprise one or more openings, and the other of the body or substrate can comprise one or more projections, disposed within or extending from respective interfacing surfaces. The complementary surface features operate to resist unwanted delamination between the body and substrate, thereby extending effective service life of the construction.

摘要： A cutter for a drill bit used for drilling wells in a geological formation includes an ultra hard working surface and a chamfer along an edge of the working surface, wherein the chamfer has a varied geometry along the edge. The average geometry of the chamfer varies with cutting depth. A depression in the shaped working surface is oriented with the varied chamfer and facilitates forming the varied chamfer. A non-planar interface has depressions oriented with depressions in the shaped working surface to provide support to loads on the working surface of the cutter when used.
