Studies on Vacuum-Sintering of TiC-40Ni-Cr-Co Cermet

Abstract

For obtaining basic informations on the vacuum-sintering of TiC base cermets containing Ni, Cr and Co as the binder metal, the cermet containing 40 wt%Ni-Cr-Co (3/1/1) was mainly studied. And some room-temperature properties such as the transverse-rupture strength, the hardness, the density, the curie temperature and the microstructure of the cermet were checked as a function of wet ball-milling times up to 200 hrs, sintering temperatures ranging from 1270° to 1440°C in usual sintering time of 1 hr and Mo additions-up to 5 wt% as a substitute for Co in the binder.
