In recent years, metal matrix composites have attracted significant importance in the research of aluminum based matrix materials reinforced with graphene nanoparticles especially in aeronautical and automobile applications. This composite materials delivered superior mechanical properties and high wear resistance. Aluminum composites are fabricated by stir and squeeze casting techniques and subsequently tribological characteristics studies were performed on both the stir cast and squeeze cast composite specimen. Taguchi's L27 orthogonal array was considered for the design of experiments. Wear characteristics studies were formed based on certain wear parameters sliding velocity (0.6, 1.2 and 2.0 m/s), sliding distance (750, 1500 and 2500 m) and load (10, 20 and 30 N). Based on the performance of the experimental results, to determine the level of influence of the parameters on the wear characteristics offriction coefficient and wear rate of the specimens © 2019 Elsevier Ltd.
