This research work was undertaken to study the effect of dry sliding wear process parameters such as load, time, and sliding velocity on the wear rate and coefficient of friction of AA8011 with 8 wt.% fly-ash composites. The response surface methodology was used to determine the most important criteria to maximize the wear rate and minimize the coefficient of friction. The experimental procedure was designed based on second-order rotatable central composite design. The optimization studies were carried out on dry sliding wear process parameter with multi-response characteristics, including the wear rate, coefficient of friction, based on multi-criteria decision-making using the TOPSIS approach. Sensitivity analysis was used to identify the important criteria and classify them by their order of importance in model validation. A confirmation test was carried out to validate the results, and the obtained optimal parameter levels were found to be very close to an ideal solution.
