Overview

This investigation evaluates the enhanced mechanical, tribological, and corrosion properties in ZrO2-reinforced aluminium composites, suggesting improvements for automotive applications.

Key Points

  • This research aims to evaluate the mechanical, tribological, and corrosion characteristics of ZrO2-reinforced aluminium-based composites.
  • Produced aluminium-based composites with 0, 5, and 15 wt% ZrO2 using a two-stage stir casting process.
  • Evaluated microstructure, mechanical properties, wear resistance, and corrosion performance using various tests including SEM and Tafel polarization.
  • Conducted nanoindentation tests to measure hardness and elastic modulus.
  • ZrO2 nanoparticles showed a uniform distribution in the alloy matrix.
  • 5 wt% reinforced composites exhibited a reduction in penetration depth by 33% compared to unreinforced alloy.
  • 5 wt% composites also showed the lowest friction coefficient (0.4) and wear rate (2.3 x 10 −3 mm3/Nm).
  • Corrosion resistance slightly improved with the addition of ZrO2 particles.
