Taguchi Analysis on the Effect of Process Parameters on Densification During Spark Plasma Sintering of HfB2-20SiC (Preprint)

Abstract

Field assisted sintering (FAST) has emerged as a useful technique to densify ultra high temperature ceramics like HfB2- 20SiC to a high density at relatively low temperatures and shorter times. The effect of various process variables on the densification during spark plasma sintering of HfB2-20SiC was studied using Taguchi analysis. The statistical analysis identified sintering temperature as the most significant parameter affecting the densification of HfB2-20SiC material. A density of 99% was achieved on sintering at 2100 deg C for 8 minutes at 30 kN pressure and heating rate of 100 K/min.
