Pure Aluminium mixed with SiC powder (size 70 micron) in 5, 10 , 15 and 20 percentage weight fractions have been stir cast and test samples have been made. The samples have been machined to produce 8 mm diameter pins for testing in Pin on Disc wear monitor under water lubricated condition. The wear behaviour of these samples has been studied by plotting the wear rates against sliding distance and velocity. The co efficient of friction has been found out under varying load and varying time. The results were compared with that of pure aluminium under similar test conditions. It has been found that the sample having 20% weight fraction of SiC with highest hardness has maximum wear resistance under such conditions.
