Cyclic oxidation resistance of rare earth oxide gel coated Fe-20Cr alloys

Cyclic oxidation resistance of rare earth oxide gel coated Fe-20Cr alloys

Rare earths (RE) have been used to increase high temperature oxidation resistance of chromium dioxide and alumina forming alloys. The RE can be added as elements (or oxides) to the alloys or applied as an oxide coating to the alloy surface. RE oxide gels, obtained by the sol-gel technique, were used...
