Immersion gold technology is a surface treatment technology that improves corrosion resistance and aesthetics by depositing a thin layer of metal or alloy on the metal surface. In the aerospace field, immersion gold technology is mainly used in the following aspects:
1. Aircraft surface treatment: The appearance of aircraft needs to have extremely high corrosion resistance and aesthetics to maintain its long-term performance. Immersion gold technology can be used to treat various surfaces of aircraft, such as fuselage, wings, tail, etc., to improve their corrosion resistance and wear resistance.
2. Spacecraft solar panel coating: Solar panels on spacecraft need to have extremely high photoelectric conversion efficiency and corrosion resistance. Immersion gold technology can be used in coating preparation to improve its corrosion resistance and extend its service life.
3. Aero engine blade coating: Aero engine blades work under high temperature and high speed conditions and require extremely high heat resistance and corrosion resistance. Immersion gold technology can be used to prepare blade coatings to improve their heat resistance and corrosion resistance and extend the service life of the engine.
4. Aerospace fastener coating: Fasteners in the aerospace field need to have extremely high mechanical properties and corrosion resistance. Immersion gold technology can be used to prepare fastener coatings to improve their corrosion resistance and wear resistance.
In general, immersion gold technology is widely used in the aerospace field and is mainly used to improve the corrosion resistance, aesthetics and service life of various materials and components.
