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.
