ABSTRACT Over the last years, there has been a growing number of studies on YSZ-alumina coatings relevant to the field of thermal barrier coatings. These coatings, either in the form of whiskers or particles reinforced, have been shown to have better properties in comparison to conventional counterparts. Apart from other aspects related to coatings, it is interesting to pose the question: is there any interaction between YSZ and alumina particles which would lead to the amelioration of the properties? Therefore, this study was launched to address the microstructural and mechanical features of YSZ-alumina composites. Since examination and detection of the phases that might be formed in the YSZ-alumina binary system would be a difficult task if the samples had been prepared by the common techniques for the coating preparation, Spark Plasma Sintering was employed to achieve dense samples to find a correlation between the microstructure and mechanical properties.

用于热障涂层的 YSZ-氧化铝复合材料的显微组织和力学性能

摘要 在过去的几年里,越来越多的关于 YSZ-氧化铝涂层的研究与热障涂层领域相关。与传统的对应物相比,这些涂层,无论是晶须形式还是颗粒增强形式,都已被证明具有更好的性能。除了与涂层相关的其他方面之外,有趣的是提出一个问题:YSZ 和氧化铝颗粒之间是否存在任何会导致性能改善的相互作用?因此,本研究旨在解决 YSZ-氧化铝复合材料的微观结构和机械特征。如果样品是通过涂层制备的常用技术制备的,那么检查和检测 YSZ-氧化铝二元体系中可能形成的相将是一项艰巨的任务,
