Abstract

Abstract: Ni-coated mixed powders were synthesized via chemical co-precipitation and hydrogen thermal reduction. Ti(C, N)-based cermets were further fabricated using as-prepared Ni-coated mixed powders successfully. Phase analysis, microstructure characterization, and properties of synthesized powders as well as the as-sintered cermets were investigated using a variety of techniques, including XRD, SEM, EDS. The results exhibited that XRD patterns of present experimental cermets only showed two diffraction peaks that correspond to Ti(C, N) hard phase and nickel binder phase. Also, microstructures of as-sintered cermets were more uniform and finer than those of traditional cermets with the same nominal composition. Meanwhile, present cermets prepared using chemical-coated method had excellent mechanical properties.
