Thermal shock resistance of YSZ, YSZ-Al2O3 and YSZ-Al2O3/YSZ coatings
Vacuum, 2019Abstract Yttria-stabilized zirconia (YSZ), YSZ-Al2O3, and YSZ-Al2O3/YSZ coatings were fabricated by plasma spraying. Their microstructures were investigated using scanning electron microscope equipped with electron backscatter diffraction attachments. Their thermal shock resistances were measured by water quenching method.

Abstract Hot corrosion is one of the main destructive factors in thermal barrier coatings (TBC s ) which comes as a result of molten salt effect on the coating–gas interface. Hot corrosion behavior of three types of plasma sprayed TBCs was evaluated: (a) usual YSZ (yttria-stabilized zirconia), (b) particle composite of (YSZ + Al 2 O 3 ) and (c ...

Thermal stability of yttria-stabilized zirconia (YSZ) and YSZ-Al2O3 coatings
Ceramics International, 2017Abstract The thermal insulation performance of yttria-stabilized zirconia (YSZ) and YSZ-Al 2 O 3 coatings deposited by atmospheric plasma spraying was evaluated using a thermal shock simulator, revealing the superiority of YSZ-Al 2 O 3 coatings due to their lower thermal conductivity.

A New Method to Analysis the Co-Sintering of NiO/YSZ-YSZ Coating
Advanced Materials Research, 2010 To explain the deformation during the co-sintering of NiO/YSZ-YSZ coating, the sintering shrinkage of NiO, NiO/YSZ and YSZ were measured by dilatometer. The coefficient of deformation variable (CDV, α) is defined to describe the difference of the sintering behaviors between the layers constrained.

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 ...
