The influence of Igbokoda silica sand and bamboo leaf ash (BLA) on the porosity and wear performance of Al6063 hybrid composites was investigated. The composites were produced using a twostep stir casting technique. Different mix ratios of the silica sand and BLA reinforced aluminium composite grades were produced. Density measurements, micro-hardness testing, abrasive wear tests and SEM examination were used to evaluate the performance of the composites. The results show that the composites became less dense with increasing BLA content. Porosity increased as the quantity of BLA exceeds 2.5 wt. %, while the hardness reduced. Single reinforced Al6063-10 wt. % silica sand composite had superior wear resistance when compared to all the composites containing more than 2.5 wt. % BLA. However, hybrid Al6063-7.5 wt. % silica sand/ 2.5 wt. % BLA has slightly improved wear resistance in comparison with single reinforced Al6063-10 wt. % silica sand composite. [ABSTRACT FROM AUTHOR] |
