Abstract

One of the greatest challenges of metallic alloys in numerous applications is due to their structural and habitual failure in service. In an attempt to subdue this failure, Aluminium metal matrix composite was developed with the inclusion of carbonized chicken bone powder (CCBP) as the reinforcing particulate. The addition of the nano-sized CCBP was carried out at different percentage weight on an Al6063 alloy. The production of Aluminium metal matrix composite (A6063-CCBP) was achieved using stir casting comprising 0, 5, 10, and 15 wt per cent of CCBP. The electrochemical and weight loss test conducted in 0.5M of hydrochloric acid on the composite reveal an improved corrosion resistance. Conventional mechanical tests; hardness and tensile test carried out on the composite using Vickers hardness technique and Universal tensile machine respectively showed that the composite now exhibits better mechanical properties. The comparison of the electrical properties from the electrical test carried out pointed to the fact that incorporation of CCBP into Al6063 provided some level of insulation. Also, the morphological change via SEM (Scanning Electron Microscope) micrograph unveiled that the inclusion of CCBP in the A6063 metal matrix reduced cleavages, showing uniform dispersion of the reinforcement along the grain boundaries and more so, minimised brittle fracture
