Abstract : Abstract: Fabrication of Aluminum LM13/MoS2/TiO2 hybrid metal matrix composite via stir casting technique was carried out to analyze the wear characteristics at an elevated temperature of 150° C using pin on disc tribometer. The parameters namely load, sliding velocity and sliding distance were varied for five levels as per the run order generated from Response Surface Methodology. From experiments, it was observed that the wear rate decreased with reduced sliding velocity initially due to mechanically mixed layer formation and then increasess. Also the results showed a reduction in wear rate with low loading and sliding distance conditions. Minimum wear rate was observed at a load of (11N), sliding velocity (1m/s) and sliding distance (848m) which was the ideal condition. Results concluded that the load applied was the significant factor over rate of wear leading to the occurrence of deep grooves along with delamination at higher loads. At minimal loads, appearance of shallow grooves in the sliding direction was observed. Major Applications of AMMC include the manufacturing of piston liners in automobiles and bearings, gears for aircraft engines which are often subjected to high friction and temperatures.
