Optimization on wear characteristics of AA2219/Nano Zirconium Diboride composites through orthogonal array

The present work investigates the wear rate of AA2219 composites that include nano Zirconium diboride (nZrB₂) reinforcement. Reinforcing percentage was changed from 0.6 to 2.4 wt% in 0.6wt% increments while fabricating composites utilizing the powder metallurgy technique. The matrix and nZrB₂ were analyzed using Energy Dispersion Spectroscopy (EDS). A pin-on-disc (POD) wear testing machine is employed to determine the wear rate (WR). This study used a Taguchi orthogonal array L16 experimental strategy to obtain how different processing variables affected the WR of a dry sliding surface. Signal to Noise ratio(S/N ratio) and the Analysis of Variance (ANOVA) technique was employed to optimize process factors like Load (L), sliding speed (S), and reinforcement percentage (R). WR shows to be most affected by L (73.65%), then S (14.17%), and R (9.80%), the projected confidence interval at the 95% level of certainty. Worn out morphological analysis is made in this study through Scanning Electron Microscopy (SEM) analysis. Having been considered, AA2219 characteristics may be greatly improved by adding nZrB₂ reinforcement particles, which makes the alloy more successful and adaptable in applications that are challenging.
