摘要： PROBLEM TO BE SOLVED: To provide a cermet excellent in defect resistance and abrasion resistance, a cutting tool using the cermet, and a manufacturing method of the cermet.
SOLUTION: The cermet has a constitution where hard phases, which each include a cored particle 10a composed of a core part 11 essentially comprising TiCN and a peripheral part 12 surrounding the core part 11 and comprises a titanium composite compound, are bound to each other via a binder phase 20 essentially composed of an iron group metal such as Co. A W-enriched phase containing a large amount of W exists in a region near the core part, i.e. within 200 nm from a boundary 13 between the core part 11 and the peripheral part 12. The cermet is excellent in abrasion resistance due to the presence of cored particle 10a and is excellent in toughness because propagation of cracks formed near the boundary 13 can be suppressed due to the presence of the W-enriched phase near the boundary 13.

摘要： PROBLEM TO BE SOLVED: To provide a cermet in which the coating work of a metallic layer is not needed separately and which has excellent joining strength with metal.SOLUTION: The cermet 1 has a hard phase 20 mainly composed of Ti and a metal bonding phase 21 including Ni and Co. Furthermore, the cermet has a base 2 formed by bonding the hard phase 20 to a metallic bonding phase 21i and a metallic layer 3 constituted of the metallic bonding phase 21c being a part of the metallic bonding phase 21i on the surface of the base 2. In the metallic layer 3, a content of Ni is larger than that of Co. In the metallic bonding phase 21i at the center in the thickness direction of the base 2, a content of Co is larger than that of Ni. Accordingly, the cermet in which the coating work of the metallic layer is not needed separately and which has the excellent joining strength with the metal can be obtained.
