Abstract

The behaviour of a commercial 13Cr ferritic SS with a LaFeO3 conversion coating is analyzed as a potentially costeffective strategy to produce IT-SOFC interconnects with electrically conductive and Cr-free stable surfaces. The growth of the passivation layer is evaluated by electrochemical methods, and the structure and morphology of the obtained coatings are analyzed by means of X-Ray Diffraction (XRD) and Scanning Electron Microscopy (SEM). Long-term oxidation experiments show high stability of the LaFeO3 conversion coating at 700°C in static moist air. Electrical conductivity properties of the coated steel in SOFC environment have been investigated measuring the Area Specific Resistance (ASR) evolution at 700°C.
