摘要:

任何大于絕對零度的物體都會向外輻射能量。在現(xiàn)代軍事戰(zhàn)爭中，戰(zhàn)斗機能否取得制空權是左右戰(zhàn)爭勝負的關鍵因素，其關鍵在于隱身技術是否可以有效避免戰(zhàn)斗機被探測到。紅外探測技術由于抗干擾能力強、檢測精度高在戰(zhàn)爭中的應用日益增加，因此對戰(zhàn)斗機紅外隱身技術的研究日漸迫切。主要通過電弧離子鍍技術在熱障涂層（主要成分為氧化釔穩(wěn)定氧化鋯，YSZ）表面制備Ag/Pt金屬層得到復合涂層YSZ-Ag/Pt，觀察復合涂層的微觀形貌，對比復合涂層熱循環(huán)前后的結合強度。結果表明，YSZ-Ag/Pt復合涂層的紅外發(fā)射率相較于熱障涂層有明顯的下降，隨著溫度升高復合涂層的紅外發(fā)射率均略有上升，其中，YSZ-Ag復合涂層的紅外發(fā)射率在各溫度段表現(xiàn)較好，YSZ-Pt復合涂層的紅外發(fā)射率上升幅度最小。與YSZ-Ag復合涂層相比，YSZ-Pt復合涂層經過熱循環(huán)后的結合強度更好。在應用的基礎上開展了對環(huán)境障涂層在紅外隱身領域的部分探索。在Yb2Si2O7（YbDS）涂層基礎上制備Ag金屬層，YbDS-Ag復合涂層紅外隱身能力顯著提高，為后續(xù)環(huán)境障涂層在紅外隱身領域的研究提供了參考。

Abstract:

Any object greater than absolute zero will radiate energy outward. In modern military warfare, the ability of fighter jets to gain air superiority is a key factor determining the war’s outcome. The key to whether fighter jets can gain air superiority is whether their stealth technology can effectively avoid detection. The application of infrared detection technology in warfare is increasing due to its strong anti-interference ability and high detection accuracy. Therefore, the research on infrared stealth technology for fighter jets is becoming increasingly urgent. The Ag/Pt metal layer was prepared on the surface of the thermal barrier coating (yttria stabilized zirconia, YSZ) by arc ion plating, and the microstructure of the composite coating was observed, and the bonding strength of the composite coating before and after thermal cycling was compared. The results showed that the infrared emissivity of YSZ-Ag/Pt composite coating decreased significantly compared to thermal barrier coating. As the temperature increased, the infrared emissivity of the composite coating slightly increased. Among them, the infrared emissivity of YSZ-Ag composite coating performed better in various temperature ranges, while the infrared emissivity of YSZ-Pt composite coating increased the least. Compared with YSZ-Ag composite coating, YSZ-Pt composite coating has better bonding strength after thermal cycling. Based on studying the application of thermal barrier coatings in the field of infrared stealth, a partial exploration of environmental barrier coatings in the field of infrared stealth has been carried out. Metal layer Ag was prepared based on Yb2Si2O7 (YbDS) coating, and the infrared stealth ability of YbDS-Ag composite coating was significantly improved, providing a reference for the research of environmental barrier coatings in the field of infrared stealth in the future.
