Experimental Investigation And Analysis Of Wear Behaviour Of Aluminium Metal Matrix Composites Reinforced With Sic And Graphite

Abstract

Among the engineering practiced material, the utilization of aluminum based material is rapidly increasing in all domains especially in aerospace and automobile industries due to excellent physical properties such as low density, low weight and low production cost. But there are constraints in frictional resistance and wear rate, thus result in poor limit of seizure and to overcome the above addition of silicon carbide and graphite is added as a supplementary and thus result in improvement in wear behavior. Stir casting was employed for producing hybrid reinforcement composites and pin on disc apparatus were used for wear testing of samples. Design of experiments DOE helps in Conducting experiments and those experimental Values are formulated through response surface methodology RSM. Scanning electron microscope SEM provides the analyzing technique to test composite specimen. The objective of this research is to investigate and optimize the influence of most predominant heat treatment parameter of Al 6061 hybrid composites and to obtain the optimal value and interaction effect for the response factor such as aging time, aging temperature, solutionizing time, solutionizing temperature thereby reducing volume. An attempt is made to improve the performance of reduced abrasion, adhesion and delamination on the surface of composite. The research is further justified with optimal value on decreased volume loss by neural networks using MATLAB.
