Abstract

The current paper investigates the wear behaviour of sic and nano sic reinforced with aluminium metal matrix composites were prepared by stir casting method. In this method five sets of both the Almmcs were produced with incorporating 2,4,6,8 and 10 wt% of sic and nano sic particulate Aluminium composites, due to increase in weight percentage of sic and nano sic particulates reduces the fracture toughness, which results in higher wear rate. Plots depict that increase in % reinforcement of sic and nano sic reduces wear up to around 5 to 7% and beyond this the wear has a tendency to increase for Al composites. Pin on disc wear tests were conducted and the results were gives the effect of increasing sic with Aluminium increases wear rate. This work focuses on developing an Aluminium metal matrix composite (AMMC) material for turbocharger components made by wrought aluminium alloy with various weight fractions of aluminium silicon carbide and nano silicon carbide composites in order to make five different forms of metal matrix composites comparison on wear behaviour were discussed.
