Abstract
Aluminum alloy hybrid composite is a demand for advanced technological applications due to their light weight with high strength and better tribological properties. The aluminium alloy (LM22) hybrid composite was developed using the sand mold process through electric arc resistance furnace and reinforced with silicon dioxide (SiO2) and graphite (Gr) particles. In this study was to evaluate the wear behaviour of LM22-SiO2-Gr hybrid composites with different percentages of SiO2 (3, 6 and 9%) and a constant weight of 9 percentage Gr reinforcement. The sliding distance (500, 1000 and 1500 m/sec), load (10, 20 and 30 N), and SiO2 reinforcement (3, 6 and 9%) are the parameters that are taken into account for wear behaviour. The wear specimens are made in accordance with ASTM standards. Wear tests are performed using the Taguchi L9 orthogonal array on-disk pin equipment and optimising wear parameters are identified in order to reduce wear rate hybrid composites. Hybrid composites, SEM images revealed unwanted displacement and attachment of wear debris.
