Abstract

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. • Large-sized columnar crystals appeared in the irradiated FeCrAl coatings. • Irradiation in the corrosion process is related to radiation-enhanced diffusion. • 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 affects the irradiation behavior of the irradiated coatings.
