High Temperature Oxidation of Fe-Cr-Al Coatings Prepared by Flame Spray Technique
In the present study, Fe-Cr and (Fe-Cr)-30at% Al coatings were prepared by a flame spray technique. The coated samples were then annealed in a vacuum furnace at 800°C for 2h. The high temperature cyclic oxidation test was performed at 800°C for up to 8 cycles to investigate its oxidation resistance....

Summary: | In the present study, Fe-Cr and (Fe-Cr)-30at% Al coatings were prepared by a flame spray technique. The coated samples were then annealed in a vacuum furnace at 800°C for 2h. The high temperature cyclic oxidation test was performed at 800°C for up to 8 cycles to investigate its oxidation resistance. XRD and SEM-EDS were used to characterize the oxidized samples. The results showed that low carbon steel was susceptible to oxidation at this temperature. Thick Fe oxides layer was formed on the steel surface. On the contrary, Fe-Cr-Al coating showed an increase in oxidation resistance of low carbon steel. The FeCr coating with 30 at % Al content exhibited the lowest mass gain after exposure for 8 cycles at 800°C. |
