【 摘 要 】

Ferritic iron-chromium-aluminum (FeCrAl) alloys and coatings with varying Cr content were subjected to in-situ irradiation-corrosion with energetic protons or electron beams in hydrogenated water for 24 h. The resulting oxide microstructures were characterized to isolate the effects of defect damage and radiolysis products on corrosion. Both proton and electron irradiation induced transpassive dissolution of Cr-rich inner oxide. (c) 2020 Elsevier B.V. All rights reserved.
