摘　　要：红外罩在航空航天和国防等领域广泛应用,其在极端环境下的薄膜失效是影响装备性能的关键问题。本文综述了红外罩薄膜的主要失效形式,包括高温导致的气动热效应、冲击损伤和表面污染等。分析了当前常用的红外罩材料如蓝宝石(Al_(2)O_(3))、锗(Ge)、硫化锌(ZnS)等的性能及其局限性,并探讨了常见修复技术,如表面清洁、抛光处理和涂层再制备。结果表明,尽管现有修复技术可以在一定程度上恢复红外罩功能,但其耐久性和修复精度仍然面临挑战。未来发展方向包括智能材料的引入,多层复合涂层技术及自适应修复技术的应用。Infrared domes(IR domes)are widely used in fields such as aerospace and defense,and the failure of thin films under extreme conditions is a critical issue affecting the performance of equipment.This paper reviews the major failure modes of IR dome films,including aerodynamic thermal effects induced by high temperatures,impact damage,and surface contamination.The performance and limitations of commonly used IR dome materials,such as sapphire(Al_(2)O_(3)),germanium(Ge),and zinc sulfide(ZnS),are analyzed.Additionally,common repair techniques,including surface cleaning,polishing,and recoating,are discussed.The results indicate that although existing repair techniques can partially restore the functionality of IR domes,challenges remain in terms of durability and repair precision.Future development directions include the introduction of intelligent materials,multilayer composite coating technologies,and the application of adaptive repair techniques.
