Ascending Order of Enhancement in Sliding Wear Behavior and Tensile Strength of the Compocast Aluminum Matrix Composites

The emerging demand of light weight alloys and composites for the engineering and structural applications leads to explore the possibility to develop new techniques to achieve materials of high performance. In the present study, Al–B₄C reinforced composite has been developed via semi solid technique. The influence of Boron carbide (B₄C) content on the dry sliding wear characteristics of Al6061 matrix composites has been assessed using a pin-on-disc wear test. Wear rate was found to increase in ascending order with B₄C particles content. On comparing the wear rate, it has been found that the wear resistance offered by coated B₄C reinforced Al 6061 alloy matrix composites is higher than both base Al alloy and uncoated composites with incorporation of harder phase. This shows the good interfacial bonding of coated B₄C and Al6061 alloy matrix phase.
