Experimental correlation of wear parameters in Al-Si-Fe alloy/breadfruit seed hull ash particulate composites

An attempt has been made to study the influence of wear parameters like applied load, sliding speed, sliding distance and weight percentage of breadfruit seed husk ash particles on the dry sliding wear of the Al-Si-Fe alloy composites. A plan of experiments, based on factorial design of four factors-two levels (4²) techniques was performed to acquire data in controlled way. Analysis of variance and linear regression were employed to investigate the influence of process parameters on the wear of the composites. The results show that applied load has the highest effect followed by sliding distance. The comparison was made between actual values and predicted values, showing an error associated with dry sliding wear of the composites to be about 2%. The results showed that the addition of breadfruit seed hull ash as reinforcing materials in Al-Si-Fe alloy composites can be used for increasing wear resistance of the composite greatly.
