dc.description.abstractIn this work, the hot corrosion (HC) resistance of bilayer thermal barrier coatings (TBC) composed of dense Ceria-Yttria Stabilized Zirconia (D-CYSZ) and Yttria-Stabilized Zirconia (YSZ) deposited using the atmospheric plasma spray (APS) technique was evaluated. Two kinds of HC tests were performed using different salt concentrations and thermal cycling (adding fresh salt between cycles) with a constant salt mixture (Na2SO4-V2O5) and constant testing temperature (900°C). The results showed that the HC mechanism changes with the testing procedure and the outer D-CYSZ layer acts as a barrier to protect the inner layers against HC degradation, although the formation of vertical cracks during the coating deposition process affected the corrosion resistance of the TBC systems
