Preparation of Aluminium Matrix Composite by using Stir Casting Method & it’s Characterization
Pages : 148-155
Driven by energy conservation and environment protection, modern engine are require to have higher power capacity accompanied by reduction in fuel consumption. Now day’s engines are more often operated at high speed and high temperature. Consequently all new engine development should meet stringent emission regulation. Therefore engine and engine components are require to be tighter and lighter with minimum intertie force. Therefore need arises to develop new material which will satisfy the requirement of modern engine. In present study we aim to manufacture composite material by reinforcing Al alloy with SiC, Al2O3, and graphite particles. The wetability between all these materials is assured by stir casting process. The fabricated composite material is tested for its mechanical, metallurgical and tribological properties. The properties of fabricated material are much superior to the base matrix Al alloy.
