Comparative Study of Plasma Sprayed Yittria and Ceria Stabilized Zirconia Properties
Thermal Barrier Coatings are subjected to spallation and destabilization due to hot corrosion.Recently, Ceria Stabilized Zirconia (CSZ)-based TBCs have been intensively investigated for the YSZreplacement because CSZ has a much lower thermal conductivity and a higher expected thermalexpansion coefficient than those of YSZ. In this research, Yttria stabilized zirconia (YSZ) andceria stabilized z...

متن کاملCharacterization of SO2-Poisoned Ceria-Zirconia Mixed Oxides
CeO2, ZrO2, and a series of CexZr1-xO2 catalysts with 1 wt% Pd were exposed to fixed exposures of SO2 under oxidizing environments and then characterized by FTIR, pulse-reactor studies with CO and O2, and temperature-programmed desorption (TPD). For exposures above 473 K, sulfates were formed on all of the materials; however, the results are consistent with the formation of bulk sulfates on CeO...
متن کاملIn Situ Nanoscale Characterization of Redox Processes in Ceria Zirconia
The ability of cerium oxides to reversibly form +3 and +4 valence oxides (CeO2 and Ce2O3) can lead to excellent oxygen storage capacity (OSC). Oxygen vacancy ordering may inhibit the reversible nature of the redox process [1]. It is well-known that doping with zirconia not only improves the life of the redox cycles but also lowers the reduction temperature [2]. Therefore nanoscale ceria-zirconi...
متن کاملWEAR REESISTANCE OF NANOSTRUCTURED AND CONVENTIONAL YTTRIA-STABILIZED ZIRCONIA COATINGS
Partially stabilized zirconia (PSZ) has been proven to be an excellent candidate as a thermal barrier coating (TBe) for hot sections in, for instance, heat or internal combustion engines and gas turbine parts. The main functions of these coatings are reducing heat losses, reducing fuel consumption, increasing efficiency, and extending durability and life. One of the main problems involved is we...
