Tribological Charactristics Of Al6061Reinforced With Granite Particulates

Aluminum matrix composites Stir casting, Microstructure, Friction and wear properties.



This study mainly focuses on synthesis of AA6061 composites reinforced with granite particles using stir casting technique. The microstructure of Al6061 alloy and Al6061-granite composites were studied using scanning electron microscope. Friction and wear behavior of Al6061 alloy and Al6061-granite composite were evaluated under varied loads and sliding velocities using tribometer in accordance with ASTM-G99 standard. SEM of composites reveals that distribution of granite particles is homogenous in matrix material. Friction and wear tests demonstrate addition of granite particles in Al6061 alloy has led to fall in wear rate and friction coefficient. Rise in the applied load enhances the wear rate and drops the friction coefficient for all the combinations studied. Increase in sliding speed increases both friction coefficient and wear rate. However, at all the loads and sliding speed, Al6061-granite composite displayed lowest wear rate and friction coefficient.
