High temperature properties of thermal barrier coatings obtained by detonation spraying
Source abstract
Abstract
NiCrAlY/YPSZ and NiCrAIY/NiAl/YPSZ thermal barrier coatings (TBCs) were successfully deposited by detonation spraying. The results indicated that the detonation sprayed TBCs included a uniform ceramic coat containing a few microcracks and a bond coat with a rough surface. The lamellar structure and the presence of cracks and impurities could reduce the thermal conductivity of the ceramic coat. Oxidation kinetics at 1000-1150degreesC of detonation sprayed TBCs have been measured and discussed. The role of a Ni-Al intermediate layer in improving the oxidation resistance of duplex TBCs has also been studied. (C) 2004 Elsevier Ltd. All rights reserved.
