摘要

This research, optimization on the tribological characteristics of zirconium diboride (ZrB2)/magnesium alloy (AZ91) synthesized using the squeeze casting technique was studied, and the Taguchi method was adopted for process optimization for wear test parameters of AZ91/12 %ZrB2 composite. The pin-on-disk machine was subjected to wear testing (ASTM G99-05). With S/N ratio and ANOVA to analyze the impact of normal load, squeezing pressure, sliding distance, and sliding velocity on a particular wear rate is very helpful. Taguchi’s technique revealed that the squeezing pressure and sliding velocity were the most crucial parameters for fixing the tribological behaviour. Based on response surface methodology, how process parameters influenced the tribology properties of the composite. The ZrB2 reinforcement prevents further material removal from the matrix under all wear circumstances. The findings of the wear test demonstrated that the wear rate is nonlinear with sliding distance and increases with the load but reduces with increasing velocity.
