Özet
The Cr₃C₂ phase of chromium carbides exhibits excellent corrosion resistance and low density, but vacancies in these materials sometimes limit their use in some applications. In order to expand the areas of use and further develop these materials, cermets containing metallic phases that provide better strength, hardness, and workability have been developed. This study examined the microstructure and mechanical properties of Cr₃C₂–Ni cermets fabricated through direct resistance rapid hot pressing. Cr₃C₂ and Ni powders were mixed in varying ratios, sintered, and analyzed using optical microscopy and X-ray diffraction for microstructural characterization. Mechanical properties were evaluated via Vickers hardness tests, density was measured using Archimedes' principle, and wear behavior was assessed. Results indicated that changes in Cr₃C₂ content significantly influenced mechanical properties and wear resistance, with the sample containing 18% Cr₃C₂ displaying superior strength and wear resistance. These findings highlight the potential of Cr₃C₂–Ni cermets in applications demanding robust and durable materials, representing a significant advancement in their development.
