Abstract
Abstract The present study was undertaken to evaluate the effect of temperature, immersion time, and different corrosive media such as HCl, H 2 SO 4 and 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 > H 2 SO 4 > KOH.
