HARDNESS AND FRATURE TOUGHNE OF PLASMA SPRAYED ZIRCONIA-CERIA-YTTRIA THERMAL BARRIER COATINGS
Iraqi Journal for Mechanical and Materials Engineering, 2018 Several studies have been made during the recent years to evaluate the plasma sprayed yttria partially stabilized zirconia thermal barrier coatings but less attention were undertaken on ceria-yttria stabilized zirconia.

Characterization of Fe implanted yttria-stabilized zirconia by cyclic voltammetry [PDF]
, 1992 The technique of cyclic voltammetry has been applied to study reduction and oxidation phenomena which are observed at low oxygen partial pressures during steady state current-overpotential measurements of the Au, O2(g)/Fe implanted yttria-stabilized ...

Molecular dynamics simulations of yttria-stabilized zirconia [PDF]
Chemical Physics Letters, 1995 Oxygen diffusion in the oxygen ionic conductor yttria-stabilized zirconia is investigated by means of the molecular dynamics simulation technique. Oxygen ions migrate by means of a discrete hopping process, mainly between neighbouring tetrahedral sites. Diffusion appears to occur in a short time and a long time regime.

Dense zig-zag microstructures in YSZ thin films by pulsed laser deposition
APL Materials, 2015 The very brittle oxygen ion conductor yttria stabilized zirconia (YSZ) is a typical solid electrolyte for miniaturized thin film fuel cells. In order to decrease the fuel cell operating temperature, the thickness of yttria stabilized zirconia thin films ...

Electrode polarization at the Au, O2(g)/yttria stabilized zirconia interface. Part II: electrochemical measurements and analysis [PDF]
, 1991 The impedance of the Au, O2 (g) / yttria stabilized zirconia interface has been measured as function of the overpotential, temperature and oxygen partial pressure. At large cathodic overpotentials (η < −0.1 V) and large anodic overpotentials (η > +0.1 V)
