Fabrication of Al Alloy Composite Reinforced with Silicon Carbide and Graphite through Stir Casting Process and Wear Analysis

Aluminum silicon carbide got wide range of applications in various sector, fields and in many industries. Aluminum matrix composites (AMCs) and Hybrid aluminum matrix composites (HAMCs) have become a great choice and various reinforcements had prospective meeting the criteria of recent aerospace and automobile industries. This aluminum is replacing some of the positions likesteels, wood, graphite etc. They are stronger, stiffer and they alsoact like heat sink which subtracts for power electronics. At present we are going to study the 6351 hybrid aluminum metal matrix composite which reinforced with graphite and silicon carbide. For this we took the method of stir casting. Although we have several methods are there for making Al-Sic composite but we preferred this technique for its simplicity and economical and thenfollowed by wear test on the material. So, as we wantdifferent types of properties when we conducted the wear test on AMCs (aluminum matrix composites) at different weight fractions of 2%, 4%, 6% and 8% of siliconcarbide and graphite which compared with Al 6351 alloy. It studies on tri-biological properties of the materials atdifferent composites. Lastly we found that if the weight fraction increases the wear properties are improved of graphite and silicon carbide in aluminum matrix.
