Abstract

A 100 h isothermal oxidation kinetics study for Crofer 22H was conducted in air and the Ar–H₂-H₂O gas mixture (p(H₂)/p(H₂O) = 94/6) in the range of 973–1123 K. The parabolic rate constant was independent of oxygen partial pressure in the range from 6.2 × 10⁻²⁴ to 0.21 atm at 1023 and 1073 K, while at 973 and 1123 K it was higher in air than in Ar–H₂-H₂O. The scales consisted of Cr₂O₃and manganese chromium spinel with an Mn:Cr ratio dependent on the oxidation conditions. Cross-scale resistance was evaluated with regards to the application of the steel in solid oxide fuel cells using a number of methods, including X-ray diffraction, scanning electron microscopy, confocal Raman imaging and area-specific resistance measurements.
