G. Bonnet et al., EFFECT OF CHROMIA AND ALUMINA COATINGS ON THE HIGH-TEMPERATURE BEHAVIOR OF F17TI STAINLESS-STEEL IN AIR - EFFECT OF A RARE-EARTH ELEMENT OXIDE, Surface & coatings technology, 80(1-2), 1996, pp. 76-79
The MOCVD technique was used to deposit thin oxide films of chromium,
aluminium and rare earth elements on stainless steel surfaces. These o
xides were deposited alone or together, successively or by codepositio
n. Coated samples were then submitted to high-temperature oxidation te
sts, under isothermal conditions at 1273 K, or under cyclic conditions
. An improvement in steel behaviour was observed in every case, partic
ularly for codeposited Ln(2)O(3)/Cr2O3: the weight gain decreased duri
ng oxidation, and the scale spallation phenomenon disappeared under cy
clic conditions, enhancing the alloy lifetime.
