2020年4月1日 · In this study, 8 wt% yttria stabilized zirconia (YSZ) was introduced to toughen the plasma-sprayed LC coatings. The mechanical performance, thermophysical properties and thermal shock resistance of the coatings were improved significantly, although a solid solution reaction between LC and YSZ occurred during spraying.

2005年2月14日 · Thermal expansion coefficients of yttria stabilized zirconia (YSZ) with the Y 2 O 3 content of 3, 6, 8 and 10 mol% were measured using a push-rod type dilatometer in the temperature range from 103 to 876 K. The thermal expansion coefficient of YSZ decreased with the increase of the Y 2 O 3 content.

尽管BSCF在低温下的面积比电阻(ASR)明显低于其他阴极材料，但其高TEC和对二氧化碳中毒的敏感性仍有待解决。 LaNi1-xFexO3-δ具有高导电性，中等TEC和低温空气稳定性。

2018年10月15日 · YSZ provides lower thermal stresses for double layer system due to its high TEC. Gd 2 Zr 2 O 7 , which is more resistant to oxygen penetration, provides less oxidation of the bond coat. They also indicate that double layered TBCs provide higher phonon scattering which provides lower thermal conductivity.

2022年9月24日 · ysz不但有着较好的断裂韧性，也有着较低热导率。 其机理是：掺杂产生的氧空位对声子有强烈的散射作用，产生了热阻，降低了材料的热导率。 总之，6-8YSZ不仅是在实际使用中久经考验的工业产品，也是被研究者们从材料机理角度证明了有着优异性能的热障 ...

釔安定氧化鋯 (英文:Yttria-stabilized zirconia, YSZ) 是一種陶瓷材料，藉由添加氧化釔改變二氧化锆的相變態溫度範圍，產生室溫下穩定的立方晶體及四方晶體。

2020年2月19日 · The most widely used TBC material is 6-8 wt.% yttria-stabilized zirconia (YSZ) because of its low thermal conductivity and high fracture toughness. Moreover, the thermal expansion coefficient (TEC) of YSZ matches well with those of metallic substrates (Ref 2).

2012年2月19日 · The value of TEC for porous 4YSZ is close to this value for nonporous material. However, the most important finding is that TEC values for obtained cermet materials are close to the TEC value of YSZ. It can indicate a potentially good adjustment between two phases: anode and electrolyte materials.

2018年10月22日 · Complex stabilization of ZrO 2 with yttrium and cerium oxides (CYSZ) allowed it to reach higher TEC (13 · 10 –6 K –1) than that of YSZ (11 · 10 –6 K –1). That is why CYSZ is regarded as an alternative to YSZ in TBCs.

2020年2月19日 · 此外，还研究了成分和微观结构对涂层热导率和热膨胀系数 (TEC) 的影响。 与 YSZ 涂层相比，YSZ-15 wt.%Al2O3 涂层具有低得多的热导率，这归因于更小的晶粒、更多的氧空位以及 Al 和 Zr 之间的较大原子量差异。 上述因素改善了声子散射，从而降低了热导率。 YSZ-15 wt 的较低 TEC。 %Al2O3 涂层归因于较小的晶格参数，这是由于 Zr4+ 位点处的替代性 Al3+ 掺杂。 晶格参数值的降低增加了晶格能量。 并且TEC与晶格能量成反比。 此外，YSZ-35 …
