Abstract Scope |
The uncertainty in the low-activity tellurium (Te) corrosion experiments has puzzled researchers for decades and makes the assessment of the tellurium embrittlement resistance of alloys for molten salt reactors impossible. The dramatic role of hydroxyl radicals in the Te corrosion behaviors of Ni-12Mo-7Cr-1Nb based superalloy was first reported. The hydroxyl radicals escape from the quartz tubes and oxidize the Cr element in the alloy to form Cr2O3 layers, which significantly suppress the Te corrosion. This work reveals The interaction between the oxidation and Tellurium corrosion in this alloy, which is the key factor in the corrosion experiment. |
