TICN BASE CERMET AND CUTTING TOOL AND METHOD FOR MANUFACTURING CUT ARTICLE USING THE SAME

摘要

A TiCN base cermet, which comprises 5 to 30 mass % of a binding phase comprising a binding metal of Co and/or Ni and hard particles bound by the binding metal, wherein a part of the hard particles comprise a core-containing structure particles composed of a core part containing TiCN and a peripheral part, and the core-containing structure particles comprise first core-containing structure particles having a peripheral part containing the binding metal and second core-containing structure particles having a core part and a peripheral part both containing the binding metal. The TiCN base cermet exhibits excellent resistance to thermal shock and to partial loss.
