Abstract: The wear and coefficient of friction (COF) behaviour of aluminium titanium (Al-Ti) alloys with varying of silicon carbide (SiC) are used as reinforcement material in the present research work. Automobile brake pads were developed by stir casting technique with 15, 20 and 25wt.% of SiC in Al-Ti alloys, respectively, instead of the traditional CI (cast iron) brake drum used for a chase machine. The normal applied load and sliding velocity varied to simulate vehicle running condition. It has been observed from the results the wear and COF for silicon carbide MMC is effectively than the CI material. The wear is varied with both sliding velocity and normal applied load. The experimental results reveals that the low wear was observed at 25wt.% of SiC than 15 and 20 wt.% of SiC. With increase of normal applied load, the wear was observed to increase whereas the COF decreases.
