Morphology and thermal conductivity of yttria-stabilized zirconia coatings

An electron beam directed vapor deposition method was used to grow 7 wt.% Y2O3–ZrO2 (7YSZ) coatings and the effects of substrate rotation upon the coating porosity, morphology, texture, and thermal conductivity were explored. As the rotation rate was increased, the texture changed from Æ111æ to Æ100æ. Under stationary deposition, the coatings were composed of straight columns, while low-frequen...

WEAR REESISTANCE OF NANOSTRUCTURED AND CONVENTIONAL YTTRIA-STABILIZED ZIRCONIA COATINGS

Partially stabilized zirconia (PSZ) has been proven to be an excellent candidate as a thermal barrier coating (TBe) for hot sections in, for instance, heat or internal combustion engines and gas turbine parts. The main functions of these coatings are reducing heat losses, reducing fuel consumption, increasing efficiency, and extending durability and life. One of the main problems involved is we...

Equilibrium Analysis of CVD of Yttria-Stabilized Zirconia

The calculations performed in this study indicate that efficient deposition of tetragonal yttria-stabilized zirconia ~YSZ! by chemical vapor deposition ~CVD! is feasible using metal chloride precursors ~Zr-Y-C-O-H-Cl system!. As reported in the literature, this work demonstrates that high oxygen content is necessary to efficiently utilize metal chloride precursors for depositing tetragonal YSZ ...

Fracture resistance of yttria-stabilized zirconia dental implant abutments.

PURPOSE An in vitro study was performed to assess the effect of different degrees of clinical reduction of zirconia abutments on the failure load of clinical assemblies. MATERIALS AND METHODS Zirconia abutments (Y-TZP Ceramic Abutment, Astra Tech) were prepared with 0, 0.5, or 1 mm of external axial reduction starting 1 mm above the height-of-contour. Abutments (n = 10) were attached to impla...

Investigation of the mechanical properties of various yttria stabilized zirconia based thin films prepared by aqueous tape casting

In this study various yttria doped  zirconia based thin films were prepared by the aqueous tape casting method. The rheological property of the paste was studies. The phase content and microstructure of the samples was investigated by X-ray diffraction and scanning electron microscope, respectively. The mechanical properties of thin films were studied by Vickers microhardness and nanoindentatio...
