บทคัดย่อ

TiC-Ni composites are promising for cutting tool applications. They have excellent combination of hardness, wear resistance, and toughness. These composites are possibly produced by liquid phase sintering via dissolution/re-precipitation process. The sintering temperature of this process is higher than eutectic temperature of the metal binder. Sintering can be enhanced by formation of a liquid phase when a sintering activator in metal binder is added. Sintering activation is evidenced by sintering temperature lowering. In this study, the effect of phosphorus as sintering activator on sintering behavior of TiC-Ni and TiC-Ni-P composites has been investigated. The TiC-Ni powders were mixed, compacted and then sintered at 1000ฐC, 1150ฐC, and 1300ฐC. Microstructures, physical and mechanical properties of the sintered TiC-Ni specimens were observed and tested. Relationship between phosphorus content, sintering temperature and mechanical properties is given in the paper.
