Optimization of friction performance of a heat treated modified za-27 alloy using design of experiments

This paper describes some aspects of concerning the effect of heat treatment on friction coefficient for Modified ZA-27 alloy. Experiments were conducted based on the plan of experiments generated through Taguchi’s technique. A L25 orthogonal array was selected for analysis of the data. Orthogonal arrays of Taguchi, the signal-to-noise (S/N) ratio, the analysis of variance(ANOVA) and regression analysis are employed to find the optimal process parameter levels and to analyze the effect of these parameters on coefficient of friction. The result shows that Normal Pressure is the more sensitive parameter.
