Overview

Randomized trial optimizes tribological performance in AA8011 composites, indicating potential for sustainable applications.

Key Points

  • This research aims to enhance the tribological performance of AA8011 composites reinforced with SiO₂ particles through optimization techniques.
  • AA8011 composites were fabricated with 9 wt% SiO₂ using stir casting.
  • Tribological testing was performed using a pin-on-disc tribometer at varying loads, speeds, and distances.
  • Grey Relational Analysis combined with fuzzy logic was employed for multi-response optimization.
  • Wear rate increased from 0.00532 mm³/m to 0.00902 mm³/m with increased load and sliding velocity.
  • The optimal parameter settings yielded a maximum Grey Fuzzy Grade of 0.717.
  • Incorporating 9 wt% SiO₂ decreased the minimum wear rate by 35% compared to the base alloy.
