A composite material contains different reinforcing elements added to the major material that forms the base matrix. In this work Aluminium 7075 matrix was reinforced with 12% TiB2and 4%, 6% and 8% Cr2O3 and the wear behavior of this composite was studied. The composite material was prepared by the process of stir casting. The rate of specific wear was measured for different reinforcements under varying velocity and load. The Scanning Electron Microscope images of the worn-out surfaces were used to investigate the wear pattern. The wear rate could further be extrapolated using fuzzy logic and were compared with the experimental results.
