Fabrication and Characteristics of YSZ–YSZ/Al2O3 Double-Layer TBC

Oxidation of Metals, 2011
A novel YSZ–YSZ/Al2O3 (YSZ means 6 wt% yttria partially stabilized zirconia) double-layer thermal barrier coating was fabricated using composite sol–gel and pressure filtration microwave sintering (PFMS) technologies. In this double-layer coating, the top layer was YSZ ceramics with a thickness of about 150 μm and the bottom layer was composed of micro-

Thermal Stability of Yttria-Stabilized Zirconia (YSZ) and YSZ-Al2O3 Coatings

Ceramics International, 2017
Abstract 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.

Thermophysical Properties of YSZ and Ni-YSZ as a Function of Temperature and Porosity

2008
The thermal diffusivity, heat capacity, thermal conductivity, coefficient of thermal expansion adn elastic properties of Ni-YSZ and YSZ are reported in the temperature interval between 20C and 1000C. Specific heat capacity (Cp)and thermal diffusivity (a) were determined by differential scanning calorimetry (DSC) and by the laser flash method ...

Agglomeration behavior of nickel particles on YSZ and TiO2-doped YSZ electrolytes

Journal of Power Sources, 2012
Abstract Agglomeration behavior of nickel thin films on the yttria stabilized zirconia (YSZ) and TiO 2 doped-YSZ electrolytes under a reducing condition and at solid oxide fuel cell (SOFC) operating temperatures was investigated by scanning electron microscopy (SEM) and scanning probe microscopy (SPM) to clarify whether this method is appropriate to

Degradation of SPS-Fabricated YSZ and Nd2O3-YSZ Ceramics in Supercritical Water

Journal of Materials Engineering and Performance, 2016
Zirconia (ZrO2) ceramics are being considered as a candidate material for thermal insulating barriers in pressure tubes used in the supercritical water (SCW) nuclear reactors. However, the literature suggests that zirconia may undergo a detrimental phase transformation which is accelerated in aqueous environments.

Structure - Property Relationships of Ni/YSZ and Ni/(YSZ+TiO2) Cermets

Fuel Cells, 2001
Cermets composed of nickel metal and Y2O3-ZrO2-TiO2 ternary ceramics were investigated by X-ray diffraction, dilatometry, electrical and microstructural measurements and are regarded as improved anode materials with respect to long-term stability. With increasing titania content it was possible to minimise the electrical and microstructural changes ...

Effect of YSZ fiber addition on microstructure and properties of porous YSZ ceramics

Journal of Materials Science, 2012
Yttria-stabilized zirconia (YSZ) fiber was introduced as the reinforcement for porous YSZ ceramics fabricated by tert-butyl alcohol-based gel-casting process and pressureless sintering. Effect of YSZ fiber addition on the microstructure and properties of porous YSZ ceramics was studied systematically.
