Effect of T6 Heat Treatment in Tribological Properties of A356 Aluminum Alloy Reinforced with Al₂O₃ Nanoparticles by Combination Effect of Stir and Squeeze Casting Method

Abstract:

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 Al₂O₃nanoparticles 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.
