ABSTRACT
In this study, the wear resistance and the density reduction of aluminium alloy when reinforced with coconut shell charcoal and cow bone ash was investigated. The design of experiment employed was D-Optimal Mixture Design. It gives the different percentage by ratio of coconut shell charcoal, cow bone ash and aluminium matrix. The casting of the composite was done using the stir casting process. It was observed from the test carried out that the density and the wear rate of aluminium alloy were reduced by 13.89% and 51.45% respectively. Also from the SEM analysis, it was observed that the reinforcement particles were uniformly distributed. The empty space between the particles of the aluminium matrix (Al) was agglomerated with the granules of the coconut shell charcoal (CSC) and the cow bone ash CBA) and there was a proper bonding of the Al, CSC and CBA, hence the improvement on the properties of the aluminium.
