发明名称 High Toughness Thermally Stable Polycrystalline Diamond
摘要 A mixture for fabricating a cutting table, the cutting table, and a method of fabricating the cutting table. The mixture includes a cutting table powder and a binder. The binder includes at least one carbide formed from an element selected from at least one of Groups IV, V, and VI of the Periodic Table. The carbide is in its non-stoichiometric and/or stoichiometric form. The binder can include the element. In certain embodiments, the binder includes one or more of the cutting table powder and a catalyst. The cutting table is formed by sintering the mixture using a solid phase sintering process or a near solid phase sintering process. When forming or coupling the cutting table to a substrate, a divider is positioned and coupled therebetween to ensure that the sintering process that forms the cutting table occurs using the solid phase sintering process or the near solid phase sintering process.
