Conventional and nanostructured YSZ coatings were deposited on the IN-738 Ni super alloy by the atmospheric plasma spray technique. The oxidation was measured at 1100°C in an atmospheric electrical furnace. According to the experimental results the nanostructured coatings showed a better oxidation resistance than the conventional ones. The improved oxidation resistance of the nanocoating could ...

In the present work, six-layered (Zirconia/Nickel) functionally graded materials were fabricated via powder metallurgy technique (PMT). The microstructure, fracture surface and the elemental analysis of the prepared components were studied, and their linear shrinkage, electrical conductivity, fracture toughness and Vickers hardness were evaluated. The results show that the linear shrinkage of t...

In solid oxide fuel cells (SOFCs) and electrolysis (SOECs), the substantial performance degradation of nickel (Ni) - yttria-stabilized zirconia (YSZ) electrode has been a growing challenge for commercialization. The microstructure Ni-YSZ is not stable during long-term operation due to Ni phase redistribution. present study, operando observations patterned film electrodes under SOFC, SOEC revers...

In this work, we show the epitaxial growth of (111)-oriented EuTiO3 thin films on (001)-oriented silicon with an in situ grown yttria-stabilized zirconia (YSZ) buffer layer by pulsed laser deposition. X-ray diffraction measurements revealed a homogeneously strained film strain dependency fluence during growth. From magnetization vs temperature measurements, confirmed that have antiferromagnetic...

In the present study, solid oxide cells (SOCs) were operated in electricity generation (solid fuel cell, SOFC) mode and hydrogen production electrolysis SOEC) mode. The electrodes fabricated with nickel-gadolinia doped ceria (Ni-GDC) nickel-yttria stabilized zirconia (Ni-YSZ) composites investigated. correlations between changes microstructure degradation of electrochemical performance are disc...

Background: Reinforcement of dental acrylics with fillers has yielded positive results. Different proportions have been added to strengthen the acrylics, but no consensus reached. Aim: The purpose this study was investigate effects addition different concentrations yttria-stabilized zirconium (YSZ) obtained from residues generated CAD-CAM milling YSZ on microstructure and mechanical properties ...
