Latest Patents

Hanaki's latest patents include a hard alloy and a cutting tool. The hard alloy features a unique composition that includes a hard phase and a binder phase. The hard phase consists of 50-70 mass % of WC, 15-30 mass % of TiCN, and up to 10 mass % of various carbides, nitrides, or carbonitrides of non-W, non-Ti metals from Groups 4, 5, or 6 of the periodic table. Additionally, the binder phase contains 6 to 12 mass % of either Co or Ni. Notably, the surface portion of the hard alloy has a higher WC content than the internal portion, with larger average grain sizes in the surface phase. His second patent involves a sintered cermet for rotary tools, which includes a hard phase with both a first and second hard phase made from carbides, nitrides, and carbonitrides of Group 4, 5, and 6 metals, primarily titanium. The X-ray diffraction measurements reveal specific peak intensity ratios that are critical for the tool's performance.
