摘要:
A cermet has a hard phase which contains W and nitrogen, and includes at least one selected from a carbide, nitride and carbonitride of a metal having Ti as a main component, and a binder phase having an iron group metal as a main component. A W amount contained in the whole cermet is 5 to 40% by weight, an interfacial phase including a complex carbonitride with a larger W amount than a W amount of the hard phase being present between grains of the hard phase, and when a W amount contained in the interfacial phase based on the whole metal element is represented by Wb (atomic %), and a W amount contained in the hard phase based on the whole metal element is represented by Wh (atomic %), then, an atomic ratio of Wb to Wh (Wb/Wh) is 1.7 or more. The cermet is excellent in fracture resistance and wear resistance.
