PCD or PCBN cutting tools for woodworking applications

摘要: A cutting tool for woodworking applications has a tungsten carbide substrate and hard layer bonded to the at high temperature pressure, i.e. where diamond or cubic boron nitride is thermodynamically stable. The comprises polycrystalline nitride, supporting cobalt phase including adjuvant alloying materials providing oxidation corrosion resistance. Typical elements include nickel, aluminum, silicon, titanium, molybdenum chromium. Such also retard transformation of from HCP FCC crystal structure temperature. an as-pressed surface parallel only about 0.3 millimeters thick. An additional secondary carbide, carbonitride metals such as titanium may be present in PCD PCBN layer.
