Wear Characterization of Aluminium/Sic/Al2O3 Hybrid Metal Matrix Composite Using Taguchi Technique

Aluminium Al6061T6 alloys are mainly used in the application of automobile and aeronautical applications.  An attempt has been made to increase the tribological property of an Al6061 alloy by adding SiC and Al₂O₃ particulates as reinforcements. The particle size of SiC particles is 400μm. Hybrid metal matrix composite is prepared by Stir casting route and Friction and wear test is done by pin-on-disc method. Al6061T6 hybrid composites are used in automobile components for reliable, long life and high performance. Experiments were conducted based on the plan of experiments generated through Taguchi’s technique. A L27 Orthogonal array was selected for analysis of the data. Purpose of investigation is to find the influence of applied load, sliding speed and sliding distance on wear rate, as well as the coefficient of friction during wearing process was carried out using ANOVA and regression equation. The objective of the model was chosen as “smaller the better” characteristics to analyse the dry sliding wear resistance. Results show that applied load has the highest influence on the wear rate followed by sliding speed and sliding distance. Sliding distance has the highest influence on the wear rate followed by applied load and sliding speed.
