  • 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.

  • Patent number: 10196314
    Abstract: Multi-step milling processes to prepare cBN composite powder forms a first powder mixture by adding a binder and a first cBN component, mills the first powder mixture for a first time period, combines a second cBN component with the milled first powder mixture to form a second powder mixture, and mills the second powder mixture for a second time period (less than the first time period) to form the cBN composite powder. A ratio of the D50 value of the second cBN component to the D50 value of the first cBN component is at least 3.0. Two-step milling with different milling times for the two cBN component fractions controls the amount of mill debris in the cBN composite powder mixture. Further processing of the cBN composite powder under HPHT conditions forms a cBN-based ceramic with an average value of a cBN particle free diameter of less than 2.0 microns.

  • 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.
