Experimental correlation using ANOVA and DOE studies on corrosion behavior of Fe and Ni-based alloy under different media

Abstract The present study was undertaken to evaluate the effect of temperature, immersion time, and different corrosive media such as HCl, H2SO4and KOH at different time intervals at 30 °C, 40 °C and 60 °C on the corrosion behavior of Fe and Ni-based alloy. The use of the design of experiment (DOE) and the analysis of variance (ANOVA) can be a useful methodology to reach this research. The analysis of the effects of each variable and their interaction on the corrosion of Fe and Ni-based alloys important role in selective best materials choice. The corrosion rate differs with different time intervals and different acid-base environments and increased with an increase in temperature from 30 to 60 °C. The study further reveals that the corrosion rate in different environment follows the order: HCl > H2SO4 > KOH.
