Studies on Some Properties of TiC-40 Ni⋅Cr⋅Mo Cermet

Abstract

Some properties such as room-temperature hardness, transverse-ru-pture strength, density and oxidation increase or microstructure of TiC-40 Ni⋅Cr⋅Mo cermet vacuum-sintered at 1280° and 1300°C for 1hr. were studied. Relation between the properties and the Ni⋅Cr⋅Mo alloy binder compositions in range of Ni>60, Cr>20 and Mo<20 wt.% was made clear. Results showed that the properties were continuously varied with increasing the content of Ni and Mo in alloy binder and the composition of binder for cermet having excellent properties was thought to be ranged 60-70% Ni, 20-25% Cr and 10-15% Mo approximately.
