Mechanical and Tribological Behavior of AA 6082 with Hybrid Metal Matrix Composites

Abstract

Abstract: Among automobile manufacturers, in recent times, a paramount importance has been given to less fuel consumption of the vehicles by utilizing lightweight and high strength materials. Metal matrix composites (MMCs) have been used commercially in the automotive market for nearly twenty years. Metal Matrix Composites (MMCs) have very light weight, high strength, stiffness and exhibit greater resistance to corrosion, oxidation, and wear. Tensile and compressive strength is an especially important property of Aluminium matrix composites which is essential for automotive application. In this study hybrid Aluminium matrix composite was fabricated through crucible casting route. Zirconium di Oxide (ZrO2) and Egg shell particles were used as reinforcement phases for the present study. The hybrid MMCwas prepared with varying the ZrO2 particles weight ratio ranging from 2% to 4% and Es were varied 3% to 5% fixed quantity 1% of magnesium. The various mechanical properties were investigated and compared with non-metal matrix alloy of Al6082. Finally mediumlevel of reinforcement enhanced the tensile and compressive strength moderately.
