Precursor-derived TiC-Ni and TiC-Cr3C2-Ni nanocomposites were synthesized by direct reduction and carburization processing. This improved carbothermal synthesis technology has proven very versatile as a wider range of compositions can be produced. Their phase structure, morphological feature and particle size were characterized by XRD and SEM. Results show that the interfacial bonding between TiC and Ni was found to be of a good quality. The TiC reinforcement was in situ formed instead of being added to the matrix. The formation mechanism of the TiC-Ni and TiC-Cr3C2-Ni nanocomposites was discussed. |
