Rare earths (RE) have been used to increase high temperature oxidation resistance of chromia and alumina forming alloys. The RE can be added as elements (or oxides) to the alloys or applied as oxide coatings to the alloy surface. This paper presents the effect of different RE oxide coatings and lanthanum chromite coatings on the high temperature oxidation behavior of Fe20Cr and

This article presents the influence of surface additions of nanocrystalline rare earth (RE) oxides CeO2, La2O3, and CeO2 + La2O3 on the isothermal oxidation behavior of Fe20Cr and Fe20Cr5Al at 1000 C. Thermogravimetric studies revealed parabolic kinetics in all
The influence of 4 nm thick CeO 2 coatings on the oxidation resistance of Fe-20Cr at 1173 K in 1 torr O 2 for periods up to 19 h was examined using 18 TEM and Finely dispersed CeO 2 became incorporated into the oxide scale and promoted the formation and retention of an adherent layer, which grew at a rate times lower than that of the base
Some previous studies also indicated that the niobium oxides were observed in the oxide scale, and were harmful to the oxidation resistance of the Ti-based alloys and the ferritic steel However, a recent study showed that the alloyed niobium had
