Evaluation of Dry Sliding Wear Properties of Stir Cast AA7050/10B4C Composites Through Fuzzy-ARAS

The present paper investigates the wear behaviour of stir cast AA7050/10B(4)C composite using Pin-on-disc tribotester. Wear properties such as wear rate, the coefficient of friction and amount of heat generation were evaluated. Microstructure of the composite analysed through FE-SEM. The Experiments were designed by Taguchi L9 orthogonal Array with following process parameters such as loads, sliding speed and sliding distance. Fuzzy-ARAS, MCDM method optimised the output parameters. From the result, it shows that the load of 10 N, sliding speed of 1m/s and sliding distance of 500 m give the minimum wear rate, minimum coefficient of friction and minimum heat generation among the selected alternatives. The consistency of the proposed Fuzzy-ARAS MCDM model is cross verified by evaluating the ranks of the alternative through Fuzzy-TOPSIS and found that the Proposed model is consistent and can be used to evaluate wear properties of AA7050-B4C composite.
