Modeling Wear Rate of Super Austenitic Stainless Steel S31254 at Elevated Temperature by Response Surface Methodology

Abstract

This paper experimentally investigated the wear rate of super austenitic stainless steel. Design of experiment of response surface methodology (RSM) was used to evaluate the influence of temperature, applied load, and sliding speed on the wear rate. The experimental results showed that the wear rate increased with the increase of the temperature from room temperature to 140°C then significantly decreased. Next, the applied load caused to increase the wear rate, while the wear rate decreased slightly with the increase of sliding speed until a specific level then distinctly decreased. Additionally, analysis of variance (ANOVA) was applied to test the significance of the variables and acceptability of the non-linear founded model. Furthermore, reasonable corresponding between experimental and predicted results was observed.
