Analysis of Wear Behaviour of a Heat Treated Modified ZA-27 Alloy by Taguchi Technique

The aim of this paper is to examine the dry sliding wear beahviour of as-received and heat treated Modified ZA-27 alloy. The alloys were prepared by conventional melting and casting route technique. The as-received samples were annealed at 3700C for 5 hours, followed by water quenching and also furnace cooling. The experiments were conducted according to plan of experiments generated through taguchi technique. A L25 Orthogonal array was selected for analysis of the data along with the analysis of variance (ANOVA) were employed to investigate the influence of process parameters on the wear behaviour of as-received and heat treated Modified ZA-27 alloy. Regression models were used to investigate the influence of process parameter on wear rate. The result reveals that Normal Pressure is the more sensitive parameter
