Frictional Study of Al 6061 Red-Mud Composite under the Influence of Different Process Parameters
Journal Title: Tribology in Industry - Year 2019, Vol 41, Issue 2
Abstract
Metal matrix composite having aluminium 6061 as matrix incorporating red mud reinforcement has been casted by employing stir casting. Scanning electron microscopy images has been taken to observe the uniformity of the red-mud reinforcement in the aluminium 6061 matrix. The inclusion of reinforcement inside the matrix of the fabricated composite has been confirmed by Energy dispersive spectroscopy. The results reveal that the coefficient of friction increases by larger sliding distance and decreases in response to higher sliding velocity. Also, coefficient of friction first increase up to second level with increase in applied load after that continuously reduced with further applying higher load. Study reveals that the coefficient of friction has been minimum at 125 micrometer particle size and has maximum value at 250 micrometer. Delta analysis shows percentage reinforcement has least effect on output i.e. coefficient of friction. Further, coefficient of friction decreases with higher aging time but again increases for 24 hour aging time. The ANOVA analysis concludes, the parameters i.e. aging time, sliding distance, sliding speed have found significant effect but the impact of particle size and load have been not comes out significant. The ANOVA revealed descending order of significance for the studied parameters has been: sliding speed, aging time, sliding distance, particle size and load.
