Optimization of Wear Rate and Coefficient of Friction of AA 7075 Alloy Using Taguchi and MABAS Approaches

Usage of lightweight materials with better tribological characteristics is significantly increasing in industrial applications. Current research work is focusing on to optimize the tribological properties of AA 7075-T6 alloy. Tribological properties like wear rate (WR) and friction coefficient (COF) of AA 7075-T6 are found using pin-on-disk apparatus. Initially, a L9 orthogonal array as per Taguchi method is used to design the number of experiments. To optimize the tribological properties in the present research work, multi-criteria decision-making (MCDM) method MABAC is considered. Moreover, an entropy method is used to evaluate the weights of the above MCDM methods. The result shows that MABAC method has provided optimal COF.
