Abstract

Fabrication of particulate composite with aluminum6061 reinforced with red-mud as reinforcement has been done by stir-casting. Uniform distribution of red-mud particles in aluminum matrix has been examined by Scanning electron microscopy. For confirmation of red-mud in the matrix, energy dispersive spectroscopy spectrum has been obtained from the surface. The results show that there has been first increase in friction force upto 12% red-mud and then decrease in friction force. Value of friction force has been found minimum at 125 µm particle size and maximum at 250 µm. Analysis reveals that friction force increases with increase in applied load and sliding distance. The effect of load and sliding speed on friction force has been reported significant by ANOVA analysis. Load has been found most effective parameter on friction force followed by sliding speed, sliding distance, particle size and aging time. Response table shows percentage reinforcement has least effect on friction force.
