Preparation and characteristics of three-layer YSZ–(YSZ/Al2O3)–YSZ TBCs
Applied Surface Science, 2011Abstract Novel three-layer YSZ–(YSZ/Al2O3)–YSZ (6 wt.% Y2O3 partially stabilized ZrO2) thermal barrier coatings (TBCs) were successfully prepared on Ni-based superalloy substrate using composite sol–gel and pressure filtration microwave sintering (PFMS) techniques.

Fabrication of Nanopore YSZ from YSZ and ZnO Mixture
Journal of Nanoscience and Nanotechnology, 2008Porous Yttria Stabilized Zirconia (YSZ) with macropore and nanopore was fabricated from sintering and leaching the mixture of YSZ and different types of ZnO. When we used nano-sized crystalline particle, porous YSZ with submicron pores was obtained. In the case of the spherical 30 nm to 100 nm ZnO particles obtained from hydrolysis of zinc acetate in ...

Fabrication of Porous YSZ from ZnO-YSZ Cermet
Solid State Phenomena, 2007Porous YSZ(8 mol% yttria-stabilized zirconia) was prepared by an acid leaching of ZnO-YSZ composite. The ZnO-YSZ composites were obtained by two different methods, a 1450 °C sintering of the mechanical mixture of ZnO and YSZ powders or a decomposition of Zn(NO3)2 deposited on YSZ and a subsequent sintering.

Effect of alumina additions in YSZ on the microstructure and degradation of the LSM–YSZ interface
Solid State Ionics, 2009The cathode-electrolyte interface in a solid oxide fuel cell is examined to understand why premature delamination is observed in alumina substituted YSZ electrolyte. From XRD. SEM and TEM observations it was concluded that after high temperature sintering a tetragonal (Mn,Al)(3)O(4) forms at the interface, which during prolonged fuel cell operation ...

YSZ/Ni–YSZ semi-cells shaped by electrophoretic deposition
Journal of the European Ceramic Society, 2007Abstract The manufacturing of Ni/YSZ self-supported films by aqueous electrophoretic deposition (EPD) for fuel cell applications is reported. The amount and the additives used in an aqueous suspension of Ni and YSZ powders have been optimized to obtain homogeneous and crack-free Ni/YSZ films on graphite substrates.

Porous NiO–YSZ and Ni–YSZ composites fabricated using NiO–YSZ composite nanopowders and WO3 additive
Materials Characterization, 2020Abstract NiO–YSZ composite nanopowders were synthesized through a hydrothermal process without an additional mixing of NiO and YSZ nanopowders. Porous Ni–yttria stabilized zirconia (YSZ) composites, Ni–YSZ composites, with high porosity (25.0–32.8%) were fabricated by reducing NiO-YSZ composites in (94% Ar + 6% H2) gas.

Spray pyrolysis deposition of YSZ and YSZ–Pt composite films
Applied Surface Science, 2005Abstract In the present paper procedures are described for spray pyrolysis deposition of YSZ films (0.1–30 μm in thickness) with 8 or 15 mole % of YO 1.5 on different substrates. Aqueous or ethylene glycol solutions of Y–Zr-citrates were used as starting material and O 2 as carrier gas.
