This study involves fabricating Ti based materials reinforced by carbon nano-tubes. CNTs were added with weight percentage (1, 2, 3, 4 and 5 wt% ) to enhance the mechanical properties of titanium. Some properties were measured for nanocomposites (CNTs/Titanium) such as microhardness, elastic modulus, wear rate in addition to microstructure by SEM. Microhardness was increased for nano-composites, which increased 421 Kg/mm2. The results of elastic modulus shown the decreasing in elastic modulus from 124 GPa to 82 GPa for nanocomposites. Wear rate results exhibited the lower wear rate of nano-composites compared with titanium due to the filling the vacancy in microstructure by CNTs. The scanning electron microscopy images showed that uniform distribution of CNTs in titanium and the lowest defect in microstructure. The good coherence between CNTs and base metal led to good mechanical properties.
