Investigation of tribological properties of aluminum oxidereinforced aluminum alloy composites

Abstract

The composites of the metal matrix are gaining attentions as they have a very significant applications especially in areas like automobiles, aerospace and also in several other engineering areas the reason for their increasing demands are due to their very good mechanical, physical and chemical properties. In this work an alloy of Al made up of the oxide of Al is synthesized with the help of a method involving a new vortex combination and the technique pressurized of die casting. The “Dry-sliding” wearing properties that are possessed by the Al alloy metal matrix of oxide of Al (Al2O3) are done by having a testing setup (apparatus) “Pin on Disc” wear test apparatus the temperature is kept 25 °C (room temperature). The alteration on the properties relating to the tribology of the MMC pin due to the speed of sliding and the normal loads when it is slided with disc of steel En36 are thus determined. The rate of wearing that increases as the value of the speed of sliding and that of normal loading increases. The rate of the specific wear is inversely proportional to the normal loads. Also the friction coefficient reduces in accordance with the value of the normal loading and the speed of sliding. The rate of wearing and the coefficient of friction Al alloy of oxide of Al MMC is having a lesser value as compared with the normal alloy of Al.
