  • Patent number: 10364190
    Abstract: A method of producing a component of a composite of diamond and a binder, wherein a Hot Isostatic gas Pressure process (HIP) is used, includes the step of enclosing a de-bound green body having compacted diamond particles in an infiltrant. The method includes the further steps of enclosing the de-bound green body and the infiltrant in a Zr-capsule that has Zirconium as a main constituent and sealing the Zr-capsule, and applying a predetermined pressure-temperature cycle on the unit formed by the de-bound green body, infiltrant and capsule in which the infiltrant infiltrates the de-bound green body and the de-bound green body is further densified in the sense that the volume thereof is decreased.

  • Patent number: 8939238
    Abstract: A sintered cutting element including a superabrasive layer supported on a substrate. The superabrasive layer includes superabrasive material and secondary phase, and the substrate includes a binder phase. The sintered cutting element is formed by a high temperature high pressure sintering process in which separate source elements melt and sweep first through the superabrasive layer, and then to the substrate to form the secondary phase and binder phase. The superabrasive layer is substantially free of or free of eta-phase, Co3W3C. Further, the portion of the substrate nearest the interface between the superabrasive layer and the substrate has equal or more binder phase than portions of the substrate further from the interface. In certain embodiments, the superabrasive material includes polycrystalline diamond, and the substrate includes cobalt tungsten carbide.
