ABSTRACT:
This invention provides a cermet alloy having a structure comprising a hard phase and a bonding phase, wherein the hard phase comprising carbide particles rich An TiC, those rich in WC and (Ti, W, MO)C or (Ti, W, Mo)(C, N) and the bonding phase comprising at least one of Co and Ni. Mo contents in the bonding phase satisfies the conditions: 1.0.ltoreq.Mo (wt %)/Ti (wt %) and 6 (wt %).ltoreq.Ti+Mo. The cermet alloy has superior hardness and toughness as well as improved heat resistance and is applicable as a material for a wet machining tool.
