Dry sliding wear performance of AA7075/MoS2 composite materials

This article aims in exploring the dry sliding wear performances on aluminum (AA7075) metal matrix composites reinforced with molybdenum disulphide which is a solid lubricant using response surface methodology (RSM). Specific Wear Rate (SWR) for AA7075 pure alloy, AA7075+2wt% and AA7075+4wt% were measured according to ASTM G99 standards pin-on-disc apparatus. Design of experiments was selected changed parameters like varying percentage (%), applied load (N), velocity (m/s) based Central Composite considering them as continuous factors. Experiments specific rate alloy conducted. The volume loss apparatus from value calculated. obtained results are analyzed mathematical model formulated methodology. optimum level has been identified experiment specify that have substantial role controlling behaviour when compared other parameter. condition experimented studying result.
