A356 alloys are attractive alternative for automotive and aeronautical applications. In this work the effects of T6 heat treatment in tribological properties of A356 alloy reinforced with Al2O3 nanoparticles of size 30nm are investigated. The percentage inclusions Al2O3 were varied from 0.5 to 1.5wt%. The particles were added with stirring at 400rpm and squeeze casting at 7500c and pressure of 600Mpa in the squeeze casting machine. The tribological properties of the samples were also investigated by pin-on-disk tests at 10,30,50and 70N, sliding speed 0.534m/s and sliding distance 1100m in dry condition. The lowest dry wear rate obtained through T6 heat treatment condition.

An attempt is made to find the mechanical and tribological properties of Al6061/Gr metal matrix composites (MMC) produced using stir casting method. It is important to note that the certain components require high hardness and wear resistance to fulfil the functional requirements, the said properties of the MMCs influenced largely on the condition with which they are produced or treated. Therefore, in the present paper the composites are tested in two stages that is before T6 heat treatment and after T6 heat treatment respectively. The composites are made with Al6061 alloy as matrix and graphite with 3%, 6%, 9% and 12% by wt is considered as reinforcement. Once the composites are prepared, they are examined for their microstructural, mechanical, and tribological properties. Further, a response surface methodology (RSM) has been used to model the wear loss and coefficient of friction for both before and after T6 heat treatment of MMCs. The non-linear regression model obtained is validated both statistically and with the help of experimental test cases. The evidence of wear phenomenon has been observed with the help of Scanning Electron Microscopy (SEM). Further, fuzzy grey relational Technique has been used to determine the multi performance index for the dry sliding wear and friction phenomenon of the developed composite.
