Abstract :

Nowadays metal matrix composites are popular in many industries due to their desirable properties. Severe plastic deformation techniques usually are popular to fabricate metal matrix composites. In this study and as its novelty, Al/Gr composites have been manufactured via a new novel technique, powder metallurgy and press bonding process. Then, as a function of Gr as additive part in this study, tribological, mechanical and microstructure properties of Al/Graphite composites were studied. The tribo surface and microstructure of composites have been investigated more over using SEM microscopy. The density and wear rate of samples increased and the hardness and friction coefficient decrease and by increasing the Gr content. Results showed that addition of Gr into Al matrix can improve the tribological properties of composite.
