Micro-compression tests were carried out on pillars of 60 ?m in diameter, milled by plasma focused ion beam porous Yttria-Stabilized Zirconia (YSZ) pellets. The fracture properties determined over a wide range porosities (33 %–63 %) for 8YSZ and at given pore volume fraction 63 % 3YSZ. mechanical from testing reproducible thanks to the homogeneity microstructures. Young’s modulus was estimated ...

Currently, ceramics are widely used in various industry branches, especially energy, chemistry, and aerospace, as well medicine. Yttria-stabilized zirconia (YSZ) having unique electrical, thermal, mechanical properties is one of the most popular for such applications. In this study, influence sintering temperature yttria percentage on microstructure behavior YSZ have been investigated. Correspo...

We propose an innovative methodology to quantify the dependence of grain growth with respect current density during flash sintering zirconia (3YSZ) (field set under a nominal limit 150 mA mm−2. This was achieved by using notch (0.5 mm deep and 1.5 wide) located in middle dog-bone specimen, allowing uneven distribution (ranging from 3 670 mm−2) while maintaining fairly homogeneous temperature (1...

The zirconia stabilized by 3mol % Y2O3 (3YSZ) was applied onto the surface of the magnesium alloy AZ91D using electrophoretic deposition (EPD) from a non- aqueous solution. A Ni-P interlayer between the substrate and YSZ coating was also prepared by electroless plating. Finally, coatings were heat treated in control atmosphere at 400 °C. The preparation, microstructure and corrosion resistance ...

To minimize alteration of the La0.6Sr0.4Co0.2Fe0.8O3−δ (LSCF)/Gd0.2Ce0.8O2−δ(CGO20)/Y0.06Zr0.94O2−δ(3YSZ) interface via strontium zirconate formation in solid oxide cells, electron beam physical vapor deposition was employed to manufacture dense, thin gadolinium-doped ceria (CGO) interlayers. CGO layers with thicknesses 0.15, 0.3, and 0.5 μm were integrated state-of-the-art 5 × cm2-large electr...

Oxidation behavior of AZ91D magnesium alloy with 3YSZ coating and aluminum interlayer was studied in air at 250 °C using electrochemical impedance spectroscopy EIS, scanning electron microscopy SEM, and X-ray diffraction XRD. The oxidation process was carried out in various duration times from 1 to 10 h. A three-electrode electrochemical cell was employed for all the EIS measurements. Also, to ...
