  • 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: 10252947
    Abstract: A cBN material and a method of making a cBN material, the method including the steps of providing a powder mixture comprising cBN grains, aluminum and a Ti(CxNyOz)a powder, subjecting the powder mixture to a milling to form a powder blend, subjecting the powder blend to a forming operation to form a green body, subjecting the green body to a pre-sintering step, at a temperature between 650 to 950° C., to form a pre-sintered body, and subjecting the pre-sintered body to a HPHT operation to form the cBN material. For the Ti(CxNyOz)a powder, 0.05?z?0.4. In addition, a cBN material includes cBN grains, an Al2O3 phase, a binder phase of TiC, TiN and/or TiCN, W and Co, whereby a quotient Q is <0.25 of the cBN material.

  • Publication number: 20170367898
    Abstract: A medical dressing having a geometrical plane of symmetry. A border portion extends along the contour of the pad. A central portion of the dressing has a smaller width perpendicular to the plane of symmetry than the widths of the adjoining portions. The medical dressing comprises a gripping tab which is coplanar with the border portion and which projects outwardly from the border portion. The medical dressing may be used for pressure ulcer prevention, such as at a heel of a human body.

  • Patent number: 9327385
    Abstract: A method of making a near-net superhard material body includes preparing granules from a mixture of superhard powder, binders, and fluids, compacting the granules to form a soft green complex-shaped body, heating the soft green body in a furnace to form a hard green body free from residual binders, embedding one or more of the hard green bodies in a containment powder or a containment means and forming a pressure cell, sintering the cell at high pressure and high temperature, and removing the containment powder from the cell or removing the inserts from the containment means to reveal one or more near-net bodies.

  • 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.
