Ti(C,N)-based Cermet Fabricated by Spark Plasma Sintering

Weihao Xiong

Abstract

Ti(C,N)-based cermet was fabricated by spark plasma sintering(SPS) technology. The formation of Ti(C,N) phase was analyzed by XRD. The microstructure of cermet prepared was observed by SEM. The hardness, bending strength and porosity of the cermet were also measured. Cermet prepared by the process at (1 350℃) for 8min duration had best performance. The effect of grain growth inhibitor VC on the properties of the cermet was also investigated. Cermet prepared with VC additive had finer microstructure but higher porosity, however, the performance of the cermet with VC was better than that without VC (additive.)
