Nanoindentation examination of yttria-stabilized zirconia (YSZ) crystal

Journal of Alloys and Compounds, 2007
Abstract The paper clarifies the specific mechanical properties of single crystal YSZ through applying the nanoindentation examination and the finite element analysis with theoretical ultrasonic measurements. The obtained results demonstrate that the lack of precise determination of the Poisson's ratio results in the significant discrepancy between ...

On the conduction pathway for protons in nanocrystalline yttria-stabilized zirconia

Physical Chemistry Chemical Physics, 2009
In this communication we elucidate a microstructural picture of proton conduction in nano-crystalline yttria-stabilized zirconia at low temperatures (Kim et al. Adv. Mater., 2008, 20, 556). Based on careful analysis of electrical impedance spectra obtained from samples with grain sizes of approximately 13 and approximately 100 nm under both wet and dry

Raman Investigation of the Nitridation of Yttria‐Stabilized Tetragonal Zirconia

Journal of the American Ceramic Society, 2003
Raman spectroscopy has been used to obtain Raman spectra of yttria‐stabilized tetragonal zirconia subject to surface nitridation induced by contact with zirconium nitride. Raman spectra recorded from regions at increasing distance from the source of nitridation have been used to obtain diffusion profiles from samples treated at ...

In Vitro Aging of Yttria‐Stabilized Zirconia

Journal of the American Ceramic Society, 1989
Yttria‐stabilized zirconia was aged in distilled water, saline, and Ringer's solution for 140, 304, and 453 d. The significant decreases in strength (13% to 22%) is attributed to the phase transformation of zirconia from tetragonal to monoclinic. The effect of aging stabilized zirconia in physiological media is still unresolved.
