摘要： Cutting elements include an ultrahard material body formed at high pressure and high temperature conditions in the absence of catalyzing material to provide a material microstructure comprising a matrix phase of bonded together ultrahard material particles and interstitial regions disposed throughout the matrix phase providing porosity of less than about 6 volume percent. The body may include a substrate attached thereto, and may include an infiltrant material disposed in a population of the interstitial regions. The body may have regions with different porosities, e.g., with a higher porosity region located adjacent a substrate interface and/or along a central region. The body may include more than one infiltrant, each located in different regions. The infiltrant may be introduced into the body during a separate high pressure/high temperature process. The body may include a region which extends a depth from a working surface that is substantially free of any infiltrant.

摘要： Systems and methods of forming components from CVD single crystal diamonds that can withstand high temperatures and pressures, for example, in a mining and/or drilling environment. This may be accomplished by transforming a graphite powder by hot-filament chemical vapor deposition (HFCVD) into a CVD single diamond crystal powder, growing a plurality of CVD single diamond crystals on a planar surface of a substrate or on a dowel. In one example, if a substrate is used as the growth surface, the plurality of CVD single crystals grow in at least one layer on the substrate and at least a portion of the plurality of CVD single diamond crystals are removed from the substrate in the form of a plurality of discrete intact sheets of CVD single diamond crystals, stacked in a mold, and sintered, for example, to form a CVD single crystal diamond table.

摘要： Polycrystalline compacts include a hard polycrystalline material comprising first and second regions. The first region comprises a first plurality of grains of hard material having a first average grain size, and a second plurality of grains of hard material having a second average grain size smaller than the first average grain size. The first region comprises catalyst material disposed in interstitial spaces between inter-bonded grains of hard material. Such interstitial spaces between grains of the hard material in the second region are at least substantially free of catalyst material. In some embodiments, the first region comprises a plurality of nanograins of the hard material. Cutting elements and earth-boring tools include such polycrystalline compacts. Methods of forming such polycrystalline compacts include removing catalyst material from interstitial spaces within a second region of a polycrystalline compact without entirely removing catalyst material from interstitial spaces within a first region of the compact.
