This paper presents the findings of an experimental investigation on the effects of applied load, sliding velocity, wt.% of reinforcement and hardness of the counterface material in dry sliding wear studies performed on red mud-based aluminum metal matrix composites (MMC). The specific wear rate and the coefficient of friction are considered as the output quality characteristics. Taguchi-based L9 orthogonal array has been used to accomplish the objective of the experimental study. Analysis of variance (ANOVA) is employed to find the optimal setting and the effect of each parameter on the output performance characteristics. It has been observed that optimal factor setting for each output performance is different. In order to minimize the two responses simultaneously, multiobjective optimization based on ratio analysis (MOORA) is adopted. MOORA revealed that the optimal combination of the dry sliding wear parameters for the multiperformance characteristics of the red mud based aluminium is the set normal load at 20?N, sliding velocity 3?m/s, % of reinforcement 20%, and counterface hardness of the material 58?HRC. 1. Introduction The metal matrix composites exhibit the significant increase in mechanical strength, wear resistance and damping properties when compared to matrix alloy [1, 2]. In many engineering applications the use of aluminium alloy is inevitable because of its superior mechanical, thermal property and it also possess low wear resistance property [3]. To increase the wear resistance of the aluminium, and its alloy is reinforced with different reinforcements, namely, short fibre, whiskers, and particulates [4]. Among the different reinforcement particulates reinforcement is gaining more attention because of its excellent isotropic property during the fabrication of composite [5]. Huda et al. [6] reported that selection of particular fabrication process depends on the type of the matrix and the reinforcement materials used to form the MMC. Particulates reinforcement can easily synthesise with matrix material using stir casting process. Sannino and Rack [7] reported that the particulates composites are good for industrial applications where performance along with cost is important. The effect of sliding velocity on the frictional and wear behaviour of aluminium MMC sliding against ferrous counterbody has been studied by a number of researchers. Unlu [8] conducted the experiments to investigate the effect of Al2O3-SiC reinforcement in aluminium metal matrix fabricated by casting and powder metallurgy method. The experiments results reveal that
