  • Publication number: 20200240216
    Abstract: A method of forming a polycrystalline diamond compact includes forming a polycrystalline diamond material at a temperature and a pressure sufficient to form diamond-to-diamond bonds in the presence of a catalyst; substantially removing the catalyst from a volume of the polycrystalline diamond material from a first surface to a first leach depth; and substantially removing the catalyst from a volume of the polycrystalline diamond material from a second surface to a second, different leach depth. A polycrystalline diamond compact includes a polycrystalline diamond material having a first volume, a second volume, and a boundary between the first volume and the second volume. The first volume includes a catalyst disposed in interstitial spaces between diamond grains. The second volume is substantially free of the catalyst. The boundary's location is selected to control thermal stability and/or impact resistance.

  • Patent number: 10350563
    Abstract: Methods for forming cutting elements comprising polycrystalline materials, methods for forming polycrystalline compacts for cutting elements of a drilling tool, methods for forming polycrystalline diamond compacts, and resulting polycrystalline compacts and cutting elements are disclosed. Grains of a hard material are introduced to a press and subjected to a high-pressure, high-temperature (HPHT) process to sinter the grains. The system conditions (i.e., temperature and pressure) are then adjusted past a phase or state change point, after which, at least one of the system conditions is held during an anneal stage before the system conditions are adjusted to final levels. The resulting compacts and cutting elements may therefore include inter-granularly bonded hard material grains with a more stable microstructure (e.g., less stressed microstructure) than a polycrystalline compact and cutting element formed without an anneal stage during the HPHT process.
