| description | Abstract AZ91D composites are ideal for weight-sensitive, high-stress aerospace applications because of their improved mechanical properties and corrosion resistance. This study focuses on the microstructural, physical, and mechanical characterization of newly developed AZ91D composites reinforced with Zirconium diboride (ZrB2) and explores their optimal performance in tribocorrosion conditions. The metal matrix composites (MMCs) were fabricated using the stir-ultrasonication-squeeze (SUS) casting technique. Additionally, an innovative approach called entropy-integrated TODIM, an MCDM method, was employed to determine the optimal process conditions. Based on the TODIM results, the optimized tribocorrosion parameters were found to be a wt.% reinforcement of 15%, an ageing temperature of 230 °C, an applied load of 30 N, and a pH value of 10. Furthermore, the desirability approach showed significant deviations in responses. Using the desirability approach and optimizing process parameters minimized corrosion pits and peak generation in the surface profile. |
