Test samples after 10000 h exposure to Pb-15.7Li Reduced activation ferritic-martensitic steels (RAFM) are considered as main structural material in future fusion systems, e.g. envisaged in the He-cooled liquid lead (HCLL) design. Thereby, these steels will be in direct contact with the breeding material Pb-15.7Li, which lead to strong corrosion attack of the structural material. Aluminum rich Fe-Al scales on RAFM steels are considered as promising corrosion barriers, which also offer T permeation reduction properties. Scales produced by Hot-dipping aluminization (HDA) exhibited some disadvantages in the past, and therefore electrochemical processes (ECA, ECX) were introduced, but have lack concerning corrosion protection data in flowing Pb-15.7Li. MotivationCorrosion barriers processed by Al-electroplating and their resistance against flowing Pb-15.7Li

The more flexible ECX process has proven to be a promising alternative to ECA
