Abstract: The present study is focussed to explore the dominant factors on metal removal of self-lubricating composite materials through rotating disc. The proposed composite material is reinforced with fly ash and Boron Nitride. As referred with ASM standard AA2218 alloy is suitable for tribological applications. Composites samples are processed by liquid metal stir casting route. AA2218 matrix alloy was reinforced with Five, Ten and Fifteen weight percentage of fly ash as hard reinforcement particles and five percentages. Levels of Boron Nitride as the second stage fortification particles in the composite material. Ninety percentage of hardness value has been correlated with tensile strength of the composite material. The hardness of the amalgamated specimens are experimented, test results shows that BHN values are significantly higher than the structural material. Dry sliding wear behavior of test samples are experiment with pin-on-disc apparatus. Affecting parameters of load on pin, weight level of support content and sliding speed on amount of wear was tested. Formation of trials through DOE approach utilizing Taguchi technique was embraced to break down the exploratory outcomes. Because of Taguchi investigation, mix of most appropriate qualities is accounted for. Motion to-commotion proportion and examination of change (ANOVA) is been utilized to explore the impact of process parameters on wear rate.
