Abstract

In this present work, Aluminum 7075 is used as matrix material with Boron Carbide asreinforcement. Two different compositions were used to prepare the composite. The composites werefabricated by Stir Casting Technique as per ASTM G99 and tested under Pin-on-Disc wear test rig. Theexperiments are conducted through conventional method and macro structural studies were carried out bySEM analysis. The results show that, in conventional method, the reinforced composite Aluminum 7075-10%B 4 C shows improvement in wear resistance than that of the Aluminum 7075-5%B 4 C, from SEM scansit is found that there is irregular distribution of B 4 C particulates in the matrix material.
