Influence Of Various Nano-Sized Tio2 Particles On The Mechanical Properties Of Aluminium Composites Synthesised By Stir Casting Method
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. In these work the influence of mechanical properties of two Nano sized Particles of 15 and 200 Nano meter Titanium-di-oxide (TiO2-p) particles reinforced with LM0 aluminium metal matrix synthesized by using bottom pouring stir casting furnace and the reinforced ratios used are 0, 4, 8 and 12 wt. %. In Nano composites the ductility of matrix material will be more when compared to micro and macro sized particulate composites. Magnesium were added to the melt in order to improve the wettability of the composites. Care has to be taken while manufacturing of Nano composites because as the Particle size decreases the clustering and agglomeration is seen in the composite. The results obtained shows that the mechanical properties of composites depends on Nano Particle size of the reinforcement added and weight % of the particulates.
