Plasma sprayed zirconia deposits have been employed in wide applications for thermal protection. Recently, the use of nanostructural surface represents an alternative for improving the performance of these coatings. The present paper reviewed the works in this field at our research group, including synthesis of nanostructural ZrO2 powders, influence of spraying parameters on microstructure and properties...
12.8mol% calcia-zirconia coatings with nanostructured surface were prepared using plasma spraying technology. The bioactivity, cytocompatibility as well as their correlation with the surface topography and nanostructure of coatings were explored. Simulated body fluid (SBF) immersion test shows that the as-sprayed zirconia coating can induce apatite precipitation on its surface, whereas the heated...
The materials surface plays an extremely important role in the response of the biological environment to the artificial medical devices. The initial protein interactions with implant surfaces are very important and therefore, it is clear that if the surface morphology, structure, composition, and properties are changed, cell functions are influenced. Nanoscale materials are thought to interact with...
Zirconia (ZrO2) thin films were deposited on silicon using a zirconium cathodic arc plasma source in the presence of oxygen following by thermal treatment at various temperatures. The structure and phase composition of the zirconia films were investigated by X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), atomic force microscopy (AFM), scanning electron microscopy (SEM) and transmission...
