  • Diamond compact
    Patent number: 6620375
    Abstract: Disclosed is a method of making a composite diamond having a cutting edge comprising a diamond compact bonded to a cemented carbide substrate, the diamond compact having a working surface, an edge of which provides the cutting edge, wherein the diamond compact comprises a first phase containing a polycrystalline mass of diamond particles and a second phase containing a diamond catalyst/solvent and ruthenium, which method includes the steps of providing a cemented carbide substrate, providing a layer of diamond particles on a surface of the substrate, providing a source of diamond catalyst/solvent and ruthenium, wherein the source of the diamond catalyst/solvent and ruthenium is the cemented carbide substrate.
