Experimental investigations on wear process parameters optimization of Austempered Ductile Iron using Taguchi technique

Rajendra M Galagali , Dr. RG Tikotkar

The influence of parameters like applied load, sliding speed and sliding distance on dry sliding wear rate of Ductile Iron (DI) / Austempered Ductile Iron (ADI) was investigated. The design of experiments (DOE) approach using Taguchi method was employed to analyze the wear behavior of Ductile Iron / Austempered Ductile Iron. Dry sliding wear tests were conducted using pin-on-disc wear testing machine. Signal-to-noise ratio and analysis of variance (ANOVA) were used to investigate the influence of parameters on the wear rate. It was determined that sliding distance was the most significant parameter influencing the wear rate of ADI followed by applied load and sliding speed. The mathematical model was obtained to determine the wear rate of DI / ADI. The confirmation tests were conducted to verify the experimental results foreseen from the mentioned correlations.
