Preparation of Nano-TI(C,N) Reinforced Ti(C,N)-based Cermets

Xu Zhi

Abstract

Ti(C,N)-based cermets were produced by using nanopowders of Ti(C,N). The effects of sintering temperature, holding time and rate of raising temperature on the properties of Ti(C,N)-based cermets containing 10wt% nanopowders of Ti(C,N) were studied. An optimum process of preparating cermets was obtained. It was the sintering temperature of 1450℃, holding time of 75min and rate of raising temperature of 3℃/min. The tensile strength was improved about 36.7% by using the process. The reinforcing mechanisms were considered chiefly to be grains refining, distributing and solution.
