Ni/CeO2 mulriple coating has been fabricated on SUS 430 steel via electrodepositing approach. 100-h initial and 3-week long-term thermal exposing to air at 800 degrees C has enunciated that the oxide scale grown on the Ni/CeO2 coated steel contains an external oxide layer of NiFe2O4 spinel, a middle oxide layer of NiO and an internal oxide layer of Cr2O3. Simultaneously, dispersive CeO2 particles embed in the oxide scale. Compared to the Ni coated steel on which the same tri-layer oxide structure without discrete CeO2 particles grows in the same exposing environment, growth rate of the internal Cr2O3 layer on the NW CeO2 coated steel has been profoundly suppressed, which subsequently lowers the oxide scale area specific resistance (ASR). Enhancement of the oxidation resistance and reduction of the oxide scale ASR are attributed to the presence of CeO2. (C) 2018 Hydrogen Energy Publications LLC. Published by Elsevier Ltd.
