چکیده
Abstract Yttria-stabilized zirconia (YSZ) coatings and Al 2 O 3 -YSZ were prepared by atmospheric plasma spraying (APS). Their microstructural changes during thermal cycling investigated via scanning electron microscopy (SEM) equipped with backscatter diffraction (EBSD) X-ray (XRD). It was found that the microstructure of two different, including crystallinity, grain orientation, phase, phase transition. These differences are closely related to cycle life coatings. There is a relationship between crystallinity crack size. Changes in orientation microscopic strain cracks. Phase transition direct cause coating failure. In this study, discussed detail. The failure mechanism comprehensively analyzed from perspective.

Manufacture of Electroless Nickel/YSZ Composite Coatings
The paper discusses optimising work on a method of processing ceramic / metal composite coatings for various applications and is based on preliminary work on processing anodes for solid oxide fuel cells (SOFCs). The composite coating is manufactured by the electroless co-deposition of nickel and yttria stabilised zirconia (YSZ) simultaneously on to a ceramic substrate. The effect on coating cha...
متن کاملChemically Vapor Deposited Ysz for Thermal Amd Environmental Barrier Coatings
Yttria-stabilized zirconia (YSZ) has been used as a thermal/environmental barrier coating for gas turbine engine blades. Current methods of fabrication include air plasma spraying (APS) and electron-beam physical vapor deposition (EB-PVD). The APS technique results in a coating that loses effectiveness with thermal cycling. The EB-PVD technique deposits a columnar microstructure which accommoda...
متن کاملThermal Conductivity, Phase Stability, and Oxidation Resistance of Y3Al5O12 (YAG)/Y2O3–ZrO2 (YSZ) Thermal-Barrier Coatings
This paper describes a new multilayer TBC that incorporates a 10 μm-thick oxygen barrier layer of yttrium–aluminum garnet (YAG) into a typical YSZ TBC system. The thermal conductivity of as-sprayed YAG/YSZ coatings was reduced due to excessive porosity and amorphous areas in the YAG layer. After long-term heat treatments, the conductivity of the multilayer was unaffected by the presence of YAG....
متن کاملEffect of NiTi Addition on the Wear Resistance of YSZ Coatings
In this study, small fraction of NiTi (5 wt%) was added to Yttria stabilized zirconia (YSZ) top coat to improve it sliding wear resistance. The measurement of width of wear tracks after wear tests under a 15 N load for 100 m sliding distances showed that the width of wear track in NiTi-YSZ coating is shorter than that in YSZ coating which depicts the higher wear resistance of NiTi-YSZ coa...
متن کاملProperties of Ni/ysz Cermets Depending on Their Microstructure
A cermet (ceramic metal composite) of Nickel and Yttria stabilized Zirconia (YSZ) is the most commonly used fuel electrode for Solid Oxide Fuel Cells (SOFC). The properties of such cermets depend strongly on their microstructure. Several Ni/YSZ cermet samples with different Ni content and Ni and 8YSZ grain size have been prepared. The thermal expansion coefficient (TEC) of these samples was mea...
