- Abstract
The objective of this research is to perform an experimental study on the tribological behavior of Al-7075 alloy reinforced with boron carbide (B4C), graphite (Gr) and fly ash. The reinforcements added to aluminium alloy in three different compositions like B4C at 3wt%/Gr at 3wt%/fly ash at 6wt%, B4C at 3wt%/Gr at 4wt%/fly ash at 7wt% and B4C at 3wt%/Gr at 5wt%/fly ash at 8wt%. The composites were fabricated through stir casting process. Hardness and wear tests were conducted for all three different composites using Brinell hardness testing machine and pin on disc wear test apparatus respectively. The inverted microscope examination was also carried out to check the microstructural view of the specimens and it was observed that the reinforcement was uniformly distributed in the primary matrix without agglomeration. From the experimental results, it was found that B4C at 3wt%/Gr at 5wt%/fly ash at 8wt% composite specimen has shown better results than other two composition specimens and may suggest for automobile industries.
