Corrosion behavior of the FeCrAl coating with different Cr and Al contents before and after Au-ions irradiation in stagnant LBE

The corrosion behavior of the FeCrAl coating with different Cr and Al contents before and after Au-ions irradiation was investigated in static LBE. The grain of the irradiated coating changed from nanocrystal to large columnar crystal. The irradiation accelerated the LBE corrosion rate, and the oxide scale changed from three layers to four layers. Nodular corrosion was found in the irradiated FeCrAl coating. The change of Cr and Al contents has a remarkable effect on the corrosion behavior of the irradiated coatings.
