Abstract

In a search for solutions to challenges posed by mechanical and structural degradation of materials in manufacture industry, Al6063/CFBP composite was developed via liquid stir casting technique by incorporating carbonized fish bone powder (CFBP) into the Aluminium metal matrix in an attempt to provide a material with superior and enduring quality. 0 %, 5 %, 10 % and 15 % of CFBP was added to the aluminium metal matrix during the casting process. The percentage of the aluminium metal matrix was of 100, 95, 90, and 85. The gravimetric and potentiodynamic polarization test conducted on the cast Al6063/CFBP composite in 0.5 M of hydrochloric acid revealed that the corrosion resisting ability of Al6063 had been improved. Universal tensile machine and Vickers hardness tester used to conduct the tensile and hardness test respectively affirmed enhanced mechanical properties. More so, the morphological evolution study of Al6063/CFBP composite via SEM micrograph unveiled the uniform distribution of CFBP with minimal rifts along the grain boundaries. Electrical characterization of Al6063/CFBP composite samples shows that the CFBP provided some impressive level of insulation to Al6063/CFBP composite samples. This was confirmed by the increase in resistivity of the samples.
