摘要: 航空发动机用热端部件及其防护涂层具有密度高、结构复杂、服役环境恶劣、承受载荷复杂等特点,采用传统的分析测试方法对其进行损伤演变、质量评估和寿命预测研究存在极大挑战,无法满足航空发动机更高温度、更高速度、更高可靠性的需求。大型科学装置中的同步辐射技术和中子衍射技术具有高穿透性、高精度、高耦合度和高通量等特点,较传统检测技术更适用于未来航空航天领域高温结构材料的研发和测试,但上述两种技术在中国相关领域的基础研究和工程应用方面仍需进一步开展工作。本文着重介绍近年来国内外采用同步辐射和中子衍射技术进行航空发动机热端部件及其防护涂层基础科学研究与实际工程应用方面的进展与现状。

Abstract: The characteristic of high temperature structural materials and coatings of aero-engine exhibit as high density, complex structure, extremely condition, complex load. It is a great challenge of traditional testing technology for high temperature structural materials and coatings on its research of failure mechanism, nondestructive testing, and life prediction, which cannot achieve the requirements of higher temperature, higher speed and higher reliability for aero-engine. The technology of the large scientific facilities of synchrotron radiation and neutron scattering technique with such excellent performance of high penetrability, high precision, high coupling and the characteristics of high flux, which is more suitable for the research and applications on aero-engine high temperature structural materials and coatings in the future. However, the improvement of investigations is still required for further investigation, such as related algorithm, special line station and typical environment. This paper focuses on the research and engineering applications of synchrotron radiation and neutron scattering techniques for high temperature structural materials and coatings of aero-engines in recent years.

Key words: superalloy, thermal barrier coating, synchrotron radiation, neutron diffraction, nondestructive testing, residual stress
