چکیده انگلیسی
An economical dip coating process was developed to synthesize uniform, crack-free, and adherent thin nanocrystalline LaCrO3 films on a ferritic stainless steel substrate for the solid oxide fuel cell interconnect applications. LaCrO3 perovskite phase was formed after annealing in air at 800 °C for 1 h for both the LaCrO3 and La2O3 precursors. The effectiveness of the coating in improving the oxidation resistance of the alloy was demonstrated by both isothermal and cyclic oxidation tests. The LaCrO3 coatings were found to cause a pronounced reduction in oxidation rate of the alloy, especially with low La-content precursors. The area-specific resistance of the oxide scales formed on the bare and coated alloy substrates was also evaluated and discussed.
