Fabrication of Aluminum Matrix Composites for Automotive Industry Via Multipass Friction Stir Processing Technique

In automotive industry, materials having excellent resistance to corrosion, good wear resistance and high strength to weight ratios are important. In accordance with the required properties; aluminum, nickel, titanium, magnesium and their alloys are mostly used in this industry. Automotive components such as engine cylinders, pistons, disc and drum brakes, engine connecting rods and Cardan shafts were all made of Aluminum Matrix Composites (AMCs). In this paper, AMCs were fabricated via multi pass Friction Stir Processing (FSP) with the aim to improve its mechanical properties and corrosion performance. 7075 Al alloy was selected as matrix and Ti-6A1-4V as the reinforcing particle.
