Changes in structure and chemical composition of Ni-coated ferritic steel ČSN 411523 are studied in the present paper. The Ni-coated material is perspective for applications in molten salts technologies. The samples were subjected to corrosion in molten mixture 60 mol. % LiF + 40 mol. % NaF at temperature 953 K, the duration exposition was 100, 300 and 1000 h. Experiments were carried out in a quasidynamic regime simulating the flow of the cooling media (the mixture of molten salts) in the pipeline system. The change of chemical composition in the vicinity of interface between the Ni layer and steel substrate was measured by SEM.
