Abstract: This present work deals with the fabrication of Al 2014 reinforced with boron carbide and short copper Basalt fiber based Hybrid metal matrix composite through stir casting process and study the wear behavior of both as cast and heat treated specimens. The microstructure of this composite was examined and observed uniform distribution of reinforced particles in the matrix. Wear experiments were conducted on pin-on-disc tester with three process parameters such as applied load, speed and sliding distance; each varied for three levels. Loads of 20 N, 40 N, 60 N; speed of 400rpm,600rpm,800rpm and sliding distance distances of 314 m, 472 m, 628 m were considered for evaluating the wear behavior of hybrid composite. Result shows that effect of both Boron carbide and Short copper coated basalt fiber composites shows good wear resistance for all composites and also observed heat treated specimens 30 to 45 % better wear resistance as compared to as cast specimens. It was observed that, severe delamination occurred as applied load increased from 40 N to 60 N. This wear analysis can be utilized to replace the conventional aircraft materials with aluminium Hybrid metal matrix heat treated composites having better wear characteristics.
