Abstract

The zeal to produce materials of high quality and low weight has made metal matrix composite (MMC) very popular among other composites .Composite materials obtained by adding particles to the metals matrix have made a remarkable progress in its development and application in aerospace and automotive industries. Zinc and aluminum matrix is one of the major metal matrixes composites in the area of revolution .In this study, the microstructural and mechanical properties of zinc aluminum alumina reinforced with coconut shell ash were examined. Coconut shell ash is an agro waste generated after the removal of coconut for the production of oil. Coconut shell was burnt on a steel plate outside in an open air for three hours and ash obtained was conditioned in the furnace at temperature of 110oC for 180mins.Six samples were prepared with different composition ,alumina, and coconut shell ash were used as reinforced phase with zinc aluminum alloy at 0,2,3,4,5and 6 wt % coconut shell ash. The agro wastes and alumina were preheated before being introduced into the zinc aluminum composite in a molten state .The mechanical properties such as tensile strength, hardness, wear and torsion were used to characterize the composite produced .The result shows a decrease in hardness, tensile, but wear loss reduces as reinforcement increases and also the shear strength increases as the volume of reinforcement increases.
