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