In this investigation, laboratory based experiments are conducted to predict the tribological characteristics of a single and hybrid reinforced nanocomposite developed through a stir casting technique. A single reinforced nanocomposite is manufactured by reinforcing 2 wt.% nano alumina (Al2O3) particles in the base matrix of Al 7075 alloy. A hybrid reinforced nanocomposite is produced with the secondary reinforcement of 4 wt.% micro silicon carbide (SiC) particles in addition to the primary reinforcement of 2 wt.% Al2O3 in the base matrix. A time bound wear analysis is performed on these composites by simulating the test conditions, which reflects the static and dynamic loading conditions of various applications viz. automotive braking, clutching and friction coupling etc. For the same loading conditions, improved wear resistance is observed for both single and hybrid reinforced nanocomposite over the unreinforced alloy. The experimental results endorse the usage of these nanocomposites for the wear applications to enhance the performance and product life. © 2017 Elsevier Ltd. All rights reserved.
