Optimization of sliding specific wear and Frictional force behaviour of Modified ZA-27 alloy using Taguchi Method

Abstract

Dry sliding wear behavior of Modified ZA-27 alloy was prepared by gravity die casting. The specific wear rate and frictional force of Modified ZA-27 alloy was studied by performing wear test using a pin-on-disc wear tester. Experiments were conducted according to plan of experiments generated using taguchi method. A L25 orthogonal array was used for analysis of data. ANOVA is used to study the influence of process parameters such as Normal load and sliding speed on specific wear rate and frictional force. Regression analyses are employed to find the optimal process parameter levels and to analyze the effect of these parameters on Modified ZA-27 alloy. The result reveals that Normal load and sliding speed were the more sensitive parameters.
