| Abstract | In this work, NiCoCrAlY coatings were deposited on a new Ni-base alloy, IC-6. The oxidation kinetic curves of alloy IC-6, K 17 and NiCoCrAlY coatings on alloy IC-6 at 900-1100 degreesC were obtained. The results indicated that the oxide scales consisted of alpha-Al2O3, NiAl2O4, NiO, as well as a small amount of NiMoO4 and MoO2. These scales occurred after alloy IC-6 exposure at 900 degreesC for 100 It. The weight loss occurred when alloy IC-6 were exposed at 1050 and 1100 degreesC due to the formation of volatile MoO3. After the NiCoCrAlY coating was deposited, the scales mainly contained alpha-Al2O3, when the specimens were oxidized at 900 degreesC, and alpha-Al2O3 and Cr2O3 at 1050 degreesC. The formation of alpha-Al2O3 and Cr2O3 scales on NiCoCrAlY coating was directly responsible for improving oxidation resistance of the alloy IC-6. (C) 2003 Elsevier Ltd. All rights reserved. |
