Investigation on Mechanical Properties and Wear Behavior of Al-Si-SiC-Graphite Composite using SEM and ED AX

摘要

In this research article mechanical properties and wear performance with regard to the tribological behavior of aluminum metal matrix composites reinforced with silicon carbide particulates and added with graphite particulates as a second reinforcement has been analysed. The method of stir casting procedure was used for the preparation of composite samples for analysis and those samples were tested for the presence of reinforcement particles using scanning electron microscope and EDAX. Uniform distribution of reinforcements and their presence was well established using characterization. The different mechanical properties have been tested and found to be better than the base alloy. Wear tests were performed to study the influence of graphite particulates and SiC particles through pin on disc tester. The experimental results of wear test reveal that, the formation of lubricate film with 4 kg of load establish the influence of graphite in the composite materials.
