Abstract :
Ceramic materials exhibit superior properties when compared to metals, in terms of thermal stability, corrosion and wear resistance. The ceramic-ceramic composites that combine boride and carbide offer an attractive combination of excellent mechanical and electrical properties. Fabrication of Titanium diboride (TiB2)/ titanium carbide (TiC) is difficult by usual techniques. Generally, this composite is fabricated by conventional sintering; hot pressing (HP) and/or hot-isostatic pressing (HIP). Both the methods require high temperatures around 3300?C. While, combustion synthesis technique is economical and energetically efficient .The final products were characterized by using scanning electron microscope (SEM), Energy dispersive x-Ray (EDX).Also, density and hardness values of the TiC-TiB2 compacts obtained decreased with increasing the C: Ti molar ratio.
