ABSTRACT: Aluminum-based composites appear to be promising material for engineering due to their excellent thermo physical properties coupled with better high temperature mechanical properties as compared to Aluminum and Aluminum alloys. Aluminum based sintered composites produced by powder metallurgy processes are now widely used in tribological engineering parts, e.g., bearing and bushes. In this project the Aluminum powder is considered as the matrix material and Graphite as a reinforcement material. Aluminum- Graphite performs are formed by powder metallurgy route using the die set assembly. The various proportions of powders are mixed respect to its volume fraction and the preforms are produced with 6:3:2 (OD: ID: H) by keeping the preforms of the matrix and reinforce materials. In this specimen had been prepared with the composition of 1% 3% 10% 20% Graphite with the remaining of aluminum powder. The specimen is prepared through powder metallurgy technique, which has larger advantage comparing to the other techniques used for the preparation of the specimen. The specimen mechanical properties had been verified through numerous tests like Micro hardness, Microstructure, Scanned Electron Microscope, X-Ray Diffraction Tests.
Keywords : Aluminum; Graphite; Hollow ring preforms; Microstructure; Scanned electron microscope; X-Ray diffraction.
