Abstract: The present work focuses on the development of the aluminum composite with the addition of alumina (Al2O3) and industrial waste i.e. Limestone Slurry Particulate (LSP) in AA6082. The LSP is considered industrial waste and is available in abundance. The particle size used in the current work varies from 10µm to 60µm with an average size of42 µm. The tribological characteristics were investigated for all the developed composites at different input parameters (like load, sliding distance and sliding velocity). The minimum and maximum value of wear rate (WR) for Al-alloy is 2.582mm3/m and 7.744 mm3/m; while for Al/Al2O3 composite is 4.345 mm3/m and 11.678 mm3/m & for Al/LSP composite is 2.303 mm3/m and 7.465 mm3/m. The minimum value of the coefficient of friction (CF) in the case of Al/LSP was 0.162. The morphological investigations of worn-out surfaces were made using scanning electron microscopy. It has been observed from morphological investigations that with the increase in reinforcement percentage in the aluminum composite, the grain boundaries thicken due to the segregation.

Keywords:  Al-composite, Coefficient of friction, Limestone Slurry Particulate, Wear rate.
