An Experimental Investigation of Metal Matrix Composites of Aluminium (Lm6), Boroncarbide and Flyash

Abstract

One of the most widely used composites is the aluminium based composites. Aluminium matrix composites refer to the class of low weight high performance aluminium is a main material. The reinforcement in AMCs may be in the structure of continuous and it also be in the form of discontinuous fibres, whiskers or particulates with volume fractions ranging from a few percent to 70%. Reinforcements commonly used in aluminium matrix composites have been extended to include organic wastes such as rice waste ash, coconut cover ash, palm oil fuel ash, and fly ash and sugar cane bagasse. Ceramic materials being used as reinforcement consists of carbides, borides, nitrides and alumina. These have been reported to produce expected physical and mechanical properties in aluminium based composites. In this experimental study the composite obtained by stir casting method by the ingredients of aluminium, boron carbide, fly ash in the different proportions. then the composite subjected to various testing machine such as pin on disc, dilatometer, abrasion testing machine to find out co efficient of friction, wear loss, wear rate for different combinations and results were compared.
