Samenvatting
Thermal barrier coatings (TBCs) are susceptible to
degradation by molten CMAS (calcium-magnesium
alumino silicate) deposits and hot corrosion , when
employed in gas turbine engines operating in a
dust-laden environment and low quality fuels . In
this study, CMAS and hot corrosion degradation of
TBCs are investigated. Yttria stabilized zirconia
(YSZ) and Ceria-yttria stabilized zirconia coatings
in contact with a CMAS dust and hot corrosion
salts deposit were subjected to heat treatment in air
at temperature 1200°C for 12h. Phase
transformations and microstructural avolution were
examined by using x-ray diffraction and scanning
electron microscopy.
