Thermal properties of ceria and yttria partially stabilized zirconia thermal barrier coatings

Effect of Superplastic Deformation on Thermal Expansion Behavior of Tetragonal Zirconia Polycrystals

“…It seems that the conventional cavities would have almost no effect on the thermal expansion, which agrees with the result that gross open pores play no noticeable role in the accommodation of thermal expansion in graphite. [10][11][12] Thermal barrier coatings of yttria stabilized zirconia containing 100% tetragonal phase have shown values similar to the present ones which are about 11:0{12:0 Â 10 À6 K À1 at 500-1250 K. 24) In the thermal expansion of nanocrystalline Ni-P alloys having different grain sizes, was shown to decrease with an increase in the average grain size from 7.5 to 127 nm. 25) In the present study, the average grain size was in the range from 0.41 to 0.48 mm, which was dependent on the amount of deformation, temperature and strain rate.…”

Microstructure, bioactivity and osteoblast behavior of monoclinic zirconia coating with nanostructured surface

“…Samples fabricated by this method exhibited a fracture toughness in the range 3.7-6.0 MPa m 1/2 , a Young's modulus of about 175 GPa, and a thermal expansion (8.7 Â 10 À6 C À1 ) closer to those of Ti alloy than hydroxyapatite [23]. Yttria-and ceria-stabilized zirconia coatings with the tetragonal or cubic phase have been deposited by plasma-spraying and are widely used in thermal protection [24][25][26]. However, to our knowledge, preparation and characterization of plasma-sprayed monoclinic zirconia coatings without a stabilizer have been seldom reported.…”

Composition, structure evolution and cyclic oxidation behavior of La2(Zr0.7Ce0.3)2O7 EB-PVD TBCs

“…[19]. It has been reported by Brandon and Taylor [21] that CeO 2 -ZrO 2 coatings exhibit an improved thermal shock resistance, a better corrosion resistance and a lower thermal conductivity as compared to the traditional YSZ coating. In addition, the slight shift in the peak positions to higher wave numbers could be attributed to a slight increase of Zr content in the CeO 2 -ZrO 2 solid solution, which can lead to change in bond energies along with bond lengths.…”
