Abstract Scope |
The corrosion evaluations of Incoloy 800H (800H) alloys with Mn and Zn inhibitors separately were performed in MgCl2-KCl for 100 hours at 800oC under argon atmosphere. The corrosion rates were estimated based on the weight loss of the 800H samples, which were 0.003±0.038mg/cm^2/day with Mn and 0.152±0.022 mg/cm2/day with Zn. 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 by using the scanning electron microscopy (SEM) equipped with energy dispersive spectrometer (EDS). In comparison, both inhibitors Mn and Zn can protect 800H alloy from further corrosion, especially the Mn. |
