Properties of Cr3C2-TiC-Ni Cermet Prepared by Infiltration

Kaizô Monma and Hajime Sutô


Abstract:

This paper describes the testing results of Cr3C2-TiC-Ni cermet prepared by the infiltration method. The cermet was prepared by mixing and compacting carbide powders and subsequently infiltrating with Ni alloy containing 35%Cr3C2 at 1,280°C for 20 min in vacuum. The best of cermets is TiC(10∼20%)-Cr3C2-Ni alloy, which has a 100-hr transverse rupture strength of 89 kg/mm2 at 850°C, and this value exceeds that of TiC-Ni cermet (67 kg/mm2). In respect of oxidation resistance also, this material is very superior.
