摘要: Three-layer Y2O3, CeO2, SiO2–Al2O3 and SiO2–Al2O3–Y2O3–CeO2 coatings were deposited by sol–gel method on the FeCrAl alloy foil substrate. The protective properties of during high-temperature cyclic oxidation changes in topography surface, structure, chemical composition surface layer examined. It has been shown that small additions cerium yttrium affect morphology growing Al2O3 scale. After 10 cycles air (T = 900 °C, t 120 h, one cycle 12 h), smallest change mass samples was observed for Y2O3 with an appropriate content. protection effectiveness to uncoated substrate after ranges from 28 66 %. scale thickness (h) designated value parabolic rate constant (kp) depended content coating.
