Effect of Al2O3-MoS2 on hardness and wear loss of Al-6061 hybrid metal matrix composite

Abstract

Abstract Aluminium Composites are presently conquering their massive practice in aerospace, marine, automobile and other industrial applications due to their vital properties such as better strength, light weight etc. The main Purpose the present research is to investigate the role of Al2O3-MoS2 on Al6061 Metal Matrix Composites (MMCs). Composites with varying weight percentages of reinforcements like Al2O3 (3, 6 and 9%) and MoS2 (3, 6 and 9%) manufactured by using stircasting method. The result shows that uniform dispersal of reinforcements with in the matrix. Increasing the wt. % of Al2O3-MoS2 in Al6061 leads to improve in hardness and exhibits the better wear resistance of the composites. SEM analysis reveals the Al6061 alloy shows the deepest and widest wear tracks and whereas in hybrid composite (Al6061/Al2O3/MoS2), width and depth of wear tracks are considerably smaller which leads to improve the wear resistance
