COMBINED FIELD ASSISTED SINTERING TECHNIQUES AND HTHP SINTERING TECHNIQUES FOR FORMING POLYCRYSTALLINE DIAMOND COMPACTS AND EARTH-BORING TOOLS, AND SINTERING SYSTEMS FOR PERFORMING SUCH METHODS |
摘要 |
Methods of forming noncrystalline diamond compacts include employing field assisted sintering techniques with high temperature and high pressure sintering techniques. For example, a particle mixture that includes diamond particles may be sintered by subjecting the particle mixture to a high temperature and high pressure sintering cycle, and pulsing direct electrical current through the particle mixture during at least a portion of the high temperature and high pressure sintering cycle. The polycrystal!ine diamond compacts may be used to form cutting elements for earth-boring tools. Sintering systems are configured to perform such sintering processes. |
