Abstract

The corrosion evaluations of Incoloy 800H (800H) alloys with Mn and Zn inhibitors were performed separately in MgCl2–KCl for 100 h at 973 K under high-purity argon atmosphere. The corrosion rates were estimated based on the weight loss of 800H samples, which were 0.003 ± 0.038 and 0.152 ± 0.022 mg/cm2/day with Mn and Zn inhibitors, respectively. The negative value of the corrosion rate indicates the increase in weight of the 800H sample after corrosion. The increased weight was attributed to the deposition of inhibitor on the surface of 800H. Besides, the composition of deposition was investigated using the scanning electron microscopy (SEM) equipped with an energy dispersive spectrometer (EDS). Both the Mn and Zn inhibitors protected 800H alloy from further corrosion, especially the Mn being better of the two.
