Abstract

Cr₃C₂-NiCr type cermets have been used in cutting industry since World War II for their relatively low sintering temperatures and relatively low densities. Their high corrosion resistance at high speeds and temperatures increases interest to these materials. In this study, the powder mixture of 75wt% Cr₃C₂-25wt% NiCr with a Ni-Cr weight ratio of 4/1 was produced as master composite at 1350°C for investigating its microstructure, micro/nano hardness and elastic modulus. SiC was added as reinforcement by decreasing the ceramic amount to study the effects on nanomechanical properties of Cr₃C₂-NiCr cermets. SEM and EDX analysis performed for identifying microstructures indicated that full densification occurs at 1350°C for master cermets. By increasing SiC ratio in cermets, the densification and relative density of doped cermets were not decreased even increased except for 8wt% SiC addition. Nanoindentation and elastic modulus tests were performed to characterize the mechanical properties of cermets.
