Abstract

Niobium alloys have excellent high-temperature, high strength, low density, and excellent processability, and is widely used in key components, such as combustion chambers, engine blades, rocket and missile nozzles. However, these niobium alloys have poor oxidation resistance and are easily affected by "pest oxidation" in high-temperature oxidation environments, which greatly limits their application in the aerospace field. This work provides a comprehensive overview of the development and application of niobium alloys, and the microstructure, mechanical properties and oxidation characteristics of three high-temperature niobium alloys (PWC-11, C-103, and Nb521) were discussed. In addition, the microstructure and phase composition evolution, oxidation behavior and failure mechanism behavior of the surface anti-oxidation coatings on high temperature niobium alloys were also investigated. Finally, some suggestions and prospects for improving the mechanical properties and oxidation resistance of high temperature niobium alloys in aerospace applications were proposed.

航空航天用铌合金的显微组织、力学性能和氧化防护

铌合金具有优异的高温、高强度、低密度和优良的加工性能，广泛应用于燃烧室、发动机叶片、火箭和导弹喷管等关键部件。然而，这些铌合金的抗氧化性较差，在高温氧化环境中容易受到“害虫氧化”的影响，极大地限制了其在航空航天领域的应用。本文综述了铌合金的发展和应用，讨论了三种高温铌合金（PWC-11、C-103和Nb521）的显微组织、力学性能和氧化特性。此外，还研究了高温铌合金表面抗氧化涂层的显微组织、相组成演变、氧化行为和失效机理。最后，对提高高温铌合金在航空航天领域的力学性能和抗氧化性能提出了建议和展望。
