ZrB2基超高温陶瓷抗氧化性研究进展

摘要

ZrB2 based ultra high temperature ceramics are widely used, because they have many excellent properties, such as high hardness, high melting point, good thermal conductivity and good thermal shock resistance. ZrB2-based ultra high temperature ceramics can be used for hot-section components in aircraft, hypersonic missiles or rockets. There are some higher requirements for their antioxidant activity. This paper has reviewed the oxidation mechanism of ZrB2-based ultra high temperature ceramics, the test method and the research progress of the oxidation resistance and so on.%ZrB2基超高温陶瓷具有硬度高、熔点高、导热性能好以及良好的抗热震性能等优点而广泛应用于飞行器、高超声速导弹、火箭的热端结构部件。超高温陶瓷的服役环境对其抗氧化性有较高的要求。文章就ZrB2基超高温陶瓷的氧化机理、测试方法以及抗氧化性能的研究进展等方面进行了综述。
