Fully stabilized zirconia/graphene composites are very promising advanced structural materials having mixed ion–electron conductivity for energy storage and conversion applications. The existing methods of the composite manufacturing have a number disadvantages that limit their practical use. Thus, search new sintering is an actively developing area. In this work, we report first time applicati...

We report on thermally resilient planar waveguides fabricated nc-YSZ by direct fs-laser inscription in transparent nc-yttria stabilized zirconia (nc-YSZ) polycrystalline ceramic. The consisted of rectangular sections (4.5 × 2 mm ) the surface sample. Optical characterization at 633 and 810 nm was performed. estimate a laser-induced refractive index contrast 10 –4 . Post-waveguide-fabrication th...

A patient’s body accepting a bone implant depends not only on the biomaterial used, but also its surface, which allows it to properly interact with cells. Therefore, research has focused improving bioactive and tribological properties of titanium alloys. Commercially pure (cp-Ti) is widely used as biomedical material. However, characterized by unsuitable properties. In this work, yttria-stabili...

OBJECTIVES To evaluate the bonding of resin-cement to yttria-stabilized tetragonal zirconia polycrystal (Y-TZP) via silica coating followed by silanization, and three one-bottle universal adhesives, with or without prior conditioning using a zirconia primer. METHODS Y-TZP specimens (n=160) were conditioned by tribochemical silica coating and silanization (CS), or alumina sandblasting with one...

A study of spark plasma sintered Ti6Al7Nb alloy reinforced with yttria stabilized zirconia (YSZ) has been carried out to assess the biocorrosion response in Hank's solution. The results indicate that microstructural changes resulting from YSZ addition were considerably different pure Ti6Al7Nb. All + composites showed a higher Vickers microhardness value 10%YSZ exhibiting most enhanced hardness ...

The aim of this in vitro study was to evaluate the effect of silica and aluminosilicate nanocomposite coating of zirconia-based dental ceramic by a sol-gel dip-coating technique on the bond strength of veneering porcelain to the yttria-stabilized tetragonal zirconia polycrystal (Y-TZP) in vitro. Thirty Y-TZP blocks (10 mm ×10 mm ×3 mm) were prepared and were assigned to four experimental groups...

Anodes for solid oxide fuel cells (SOFCs) have been prepared by electrodeposition of either Co or Ni into a layer of porous yttria-stabilized zirconia (YSZ), 60 μm thick. The YSZ, having 65% porosity, was prepared by tape casting with graphite pore formers and was attached to the dense YSZ electrolyte. After adding 10 vol % CeO2 by impregnation of aqueous solutions of CeNO3)3, followed by calci...

• The NLO capacity of YSZ is comparable to YSZ. Evidence significant vibrational contributions the optical third order nonlinearities Yttria stabilized hafnia are reported. electronic properties YSH do not constitute subjects strong spin orbit coupling effects. This work reports for first time theoretical nonlinear susceptibilities bulk phases which key telecommunication technologies and integr...

objective: a clinical challenge of using zirconia frameworks is to achieve adequate bond with different substrates. this study aimed to evaluate the effect of bioglass and silica coating of zirconia substrates on microshear bond strength of resin cement to tetragonal zirconia. methods: this laboratory experimental study was conducted on zirconia discs. a total of 120 ytzp zirconia (zirkonzahn) ...
