Abstract

•Protective action of dense and porous spinel coatings on Crofer 22 APU was compared.
•Reduction and re-oxidation produces denser coatings than heat treating in air only.
•Coating density has minor influence on oxidation resistance at 800 °C in air.
•Dense coating resulted in three times lower Cr evaporation rate than porous coating.
