Abstract
This paper deals with optimization of wear behaviour on aluminium metal matrix composites (AMC) filler by coconut shell ash (CSA) on pin-on-disc setup. The Al-CSA composites are fabricated with various volume percentages such as 5, 10 and 15% of CSA using compo casting technique. The properties of Al-CSA composites have been improve with increasing volume of CSA in base matrix. The experiments are carried out with three process parameters: load, percentage of CSA and sliding distance; and three adequate responses: wear (µm), wear rate (mm3/m) and coefficient of friction. This studied, a hybrid approach (that is, Grey-fuzzy) has been applied to optimizing the several responses. The fuzzy logic concept has been used for handling the uncertainty in the decision-making process. Analysis of variance (ANOVA) shown that the highest influencing parameter is load, followed with sliding distance and percentage of CSAp to the overall tribological performance.
