  • 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.

  • Publication number: 20180073108
    Abstract: A rock drill button having a body of sintered cemented carbide that has hard constituents of tungsten carbide (WC) in a binder phase of Co, wherein the cemented carbide has 4-12 mass % Co and balance WC and unavoidable impurities. The cemented carbide also has Cr in such an amount that the Cr/Co ratio is within the range of 0.043-0.19, and that the WC grain size mean value is above 1.75 ?m.
