Optimization of tribological behaviour of hybrid composites based on A356 and ZA-27 alloys

Abstract

Optimization of tribological behaviour of hybrid composites based on A356 and ZA27 alloys reinforced with 10 wt. % SiC and 0, 1 and 3 wt. % Gr is presented in this paper. Optimization was performed using the Taguchi method and the artificial neural network (ANN). Hybrid composites were obtained by compocasting procedure. The analysis shows that hybrid composites based on A356 alloy have better tribological characteristics, while the one reinforced with 10 wt. % SiC and 1 wt. % Gr shows the least wear.
