Abstract : The Aluminium based Metal Matrix Nano Composites can be used in numerous applications because of their splendid Mechanical, Tribological Properties and Light Weight compared to Micro composites. The Nano Particulate Composites were synthesized by using bottom pouring stir casting technique in the wt. % of 0, 4, 8 and 12 with the 60nm Particle of TiO2 and LM0 Aluminium alloy. The Brinell Hardness Number and resistance to Wear rate will be gradually increased when compared with micro sized particulate composites because there will be more number of smaller nano particles in the given volume which act as barrier and increases resistance to wear. The wear test was conducted by varying speed and load and by keeping sliding distance constant for 3000m, the varied speed are 200, 300 and 400 rpm and the load applied are 1, 2 and 3 kg respectively. The rate of wear is measured in terms of height loss in microns. The 12 wt. % TiO2 particles will have more wear resistance compared with any other wt. % because of brittle nature of nano TiO2 particles. 5 wt. % of Magnesium was added to the melt in order to improve the wettability of the composites. Keywords - Nano TiO2 Particulate Composites, LM0 Alloy, Stir Casting, Hardness and Wear Properties.
