ABSTRACT:
A cermet has a hard phase and a binder phase. The hard phase is formed by about 70% to about 95% by weight of elements including titanium, tantalum, tungsten, carbon and nitrogen. The elements have atomic ratios so as to satisfy the relationships of 0.05.ltoreq.b/(b+a).ltoreq.0.20, 0.04.ltoreq.c/(c+a).ltoreq.0.20 and 0.15.ltoreq.y/(x+y).ltoreq.0.60, where a, b, c, x and y denote atomic ratios of titanium, tantalum, tungsten, carbon and nitrogen, respectively. The binder phase is formed by about 5% to about 30% by weight of at least one metal of cobalt and nickel. Additionally, there is disclosed a process for producing such a cermet.
