APPLICATION OF TAGUCHI METHOD IN THE OPTIMIZATION OF ZINC BASED COMPOSITE

Abstract

Tribological behaviour of composite with the ZA-27 alloy base reinforced by 5% SiC is considered in this paper. The optimization of tribological behaviour was conducted using the Taguchi method. Composite was prepared by the compocasting procedure. Tribological experiments were carried out using a block on disc tribometer with the variation of three different load values (10, 20 and 30 N), three sliding speed values (0.25, 0.5 and 1 m/s) and sliding distance value of 600 m. All the experiments were conducted under dry sliding test conditions. The analysis of the wear rate was executed using the ANOVA method of analysis. The sliding speed has the greatest impact on the wear rate (81.72%), then the SiC content (11.07%), and the least the contact load (5.07%).
