| Abstract | The influence of Y 2 0 3 coatings on the oxidation behaviour of Fe-25wt%Al and Ni-32wt%Al has been investigated at 1100 and 1200 OC. Samples were sputter coated with 4 nm of Y 2 0 3 and oxidized sequentially in 1602 and Oxide scales have been characterized using SIMS, XPS, SEM, X-ray and electron diffraction. A comparison is made between the growth of oxide on Y203-coated and uncoated alloys. The major effects of the yttria coating at 1100 OC are to delay the formation of a-A1203 and to increase the oxidation rate. At 1200 O C a two-layered scale is formed instead of a single layer; all of the yttrium is contained in a non-adherent outer layer. |
