Evaluation of oxidation and thermal cyclic behavior of YSZ, Gd2Zr2O7 and YSZ/Gd2Zr2O7 TBCs

Surface and Coatings Technology, 2019
Abstract Thermal barrier coatings (TBCs) are widely used to increase gas turbine efficiency and to prolong the lifetimes of superalloy substrates. Yttria (7–8%) stabilized zirconia (YSZ) is used as a state of the art TBC top coating material. In recent years, rare earth zirconates have drawn interest as top coating materials due to their high phase ...

Electronic Activation via Targeted Interface Engineering: Unlocking High‐Performance CO2 Electrolysis in Commercial Electrodes

EcoEnergy, EarlyView.
Interfacial charge transfer from LSC to PrO2 induces a local electric field and promotes oxygen vacancy formation, which together enhance CO2 adsorption, facilitate CO32− intermediate formation, and significantly boost the high‐temperature CO2 electrolysis performance of PrO2–LSC heterostructured electrodes.

Deposition of NiO/YSZ Composite and YSZ by Suspension Plasma Spray on Porous Metal

International Thermal Spray Conference, 2010
Abstract The use of a liquid feedstock carrier in suspension plasma spray (SPS) permits injection of fine powders, providing the possibility of producing sprayed coatings that are both thin and dense and have fine microstructures.

Rational A‐Site Multi‐Cation Design Enables Durable Fe‐Based Perovskite Air Electrodes for Fast Oxygen Reduction

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A‐site multi‐cation doping in Pr0.5Ba0.5FeO3−δ produces Pr1/6La1/6Nd1/6Ba1/6Sr1/6Ca1/6FeO3−δ with reduced size mismatch and charge‐transfer energy, showing the highest electrocatalytic activity among those of Pr0.5Ba0.5FeO3−δ. Although Pr0.5Ba0.5FeO3–δ (PBF)‐based perovskite cathodes are prevalent for solid oxide fuel cells (SOFCs), their practical ...

Development of Calcium‐Based Coatings to Mitigate Vanadate Corrosion

Materials and Corrosion, EarlyView.
Ca‐rich coatings can suppress the corrosive attack of molten V2O5 by forming Ca2 V2 O7 and Ca V2 O6. For this, a large Ca‐reservoir is key to mitigate corrosion at 600°C and 700°C. ABSTRACT Vanadate corrosion occurs in devices powered by heavy fuel oil, such as stationary turbines.

High‐Temperature Corrosion of Unpassivated Carbon Steel in Simulated Boiler Water: Electrochemical Thresholds and Mechanisms for Chloride and Sulphate Contamination

Materials and Corrosion, EarlyView.
Through a combination of in situ electrochemical corrosion rate measurements and FactSage thermochemistry modeling, chloride and sulphate ions were found to influence the corrosion of carbon steel in high‐temperature boiler water through distinct mechanisms: chloride acidifies the solution, raising iron solubility, while sulphate leaves solubility ...
