Structure and thermal properties of heat treated plasma sprayed ceria–yttria co-stabilized zirconia coatings

Microstructural, mechanical and thermal characteristics of zirconia-based thermal barrier coatings deposited by plasma spraying

“…The porosity of the CYSZ layer is close to 10 %. As reported elsewhere, CYSZ is a good TBC candidate in substitution of YSZ, because it exhibits higher CTE (12.6 x 10 -6 against 10.7 x 10 -6 K -1 ), higher hardness (6.5 against 5.9 GPa), higher phase stability and good resistance to high-temperature sintering [19,32]. The CTE of CYSZ coating is more close to that of the bond coat material and not quite different from that of LZ coating herein manufactured.…”

Ca-P spots modified zirconia by liquid precursor infiltration and the effect on osteoblast-like cell responses

“…Ca-P spots formation would avoid the crack occurring for its cluster-structure. Researchers focus on the fabrication of bioactive coatings on zirconia surface [19][20][21] , however, the coatings could not combine with substrates well due to their different physicochemical properties, such as mismatched thermal expansion coefficients 28) . In this study, Ca-P spots anchored with the zirconia (Figs.…”

Porosity and microstructural features of plasma sprayed Yttria stabilized Zirconia thermal barrier coatings

“…The YSZ top-coats are deposited either by air plasma spray (APS) or by electron beam physical vapor deposition (EB-PVD) techniques with thickness ranging from 250 to 375 μm [2,[5][6][7][8]. The APS technology is extensively used in industrial scale to deposit TBCs because of high deposition rate, ability to coat large components, economical efficiency and ability to produce coatings with enhanced thermal barrier properties and corrosion resistance.…”
