TiC – based cermets are known for their outstanding corrosion and high temperature wear resistance; they are most commonly used in metal cutting tools, but their unique combination of properties offers wide scope to the materials design engineer .Titanium carbide (TiC) is the material of commercial interest because it possesses a range of desirable properties. It is extremely hard, being one of the hardest known metal carbides. TiC exhibits an excellent thermal stability and has a very high melting temperature of approximately 3100 oC . This combination of very high hardness, a high melting temperature and an excellent thermal and chemical stability makes TiC suited to the TiC-NiMo cermets. However, one of the disadvantages of using TiC for commercial applications is that it is difficult to produce. Most of the industrial TiC powders are produced through the reduction of TiO2 with carbon at temperatures of 1900 – 2100 oC for 10 to 20 hours. This method has serious disadvantages due to the high cost of equipment and high power consumption because of the very high synthesis temperature.
