1 Οκτ 2021 · For this purpose, a simple but effective methodology for comparing the transport behavior was proposed in this study, which involves high-temperature interactions between YbYSZ ceramic powders and CMAS melts.
15 Ιουν 2022 · Y 2 O 3 doped ZrO 2 (YSZ) ceramic material is used to protect alloy components worked in high-temperature. But its phase transformation between tetragonal phase and monoclinic phase...
1 Σεπ 2019 · To avoid these mentioned problems, Y 2 O 3-stabilized ZrO 2 whiskers (YSZ W) are synethsized in this work for purpose of simultaneously taking the two roles of the YSZ p particles and SiC whiskers for toughening and strengthening the Al 2 O 3 ceramics.
The conducted research focused on the mechanical (Young’s and shear moduli, flexural strength, hardness, and fracture toughness), thermal (thermal conductivity and coefficient of thermal expansion), and electric (dielectric properties) characterization of MgO-Al2O3, MgO-CaZrO3, and stable YSZ ceramic composites.
8 Μαρ 2005 · This paper reviews the uses and properties of ceramics and ceramic coatings variously employed as articulation devices in hip, knee, shoulder, and other joints, either as self-mated surfaces,...
1 Αυγ 2023 · Y 2 O 3 –ZrO 2 –HfO 2 solid-solution powders with different HfO 2 contents were prepared via high-pressure hydrothermal synthesis and sintered into ceramics. The phase compositions and microstructures of the solid solutions formed were investigated in detail.
19 Μαΐ 2020 · The presence of tie line between MgO and Y 4 Zr 3 O 12 in the temperature range between 1493 and 1573 K was confirmed. The eutectic melting in the MgO-Y 2 O 3 -ZrO 2 system was established using DTA followed by SEM/EDX microstructure investigation.
