Abstract:
A TiC-based cermet body includes TiC and WC so that the atomic ratio Ti/W is between 2 to 5, and cobalt as the binder phase is present in an amount of between 5 to 25 vol %. Further, the cermet body has at least one element from group V of the periodic table, Mx, so that the atomic ratio Ti/Mx is between 4 to 20 and the atomic ratio W/Mx is between 1 to 6. The cermet body also has Cr in an amount such that the atomic Cr/Co ratio is from 0.025 to 0.14. The cermet body includes both undissolved TiC cores with a rim of (Ti,W,Mx)C alloy as well as (Ti,W,Mx)C grains which have been formed during sintering. A method of making a cermet body is also disclosed.
