Riepilogo delle prestazioni e dei metodi di prova per i rivestimenti aerospaziali
Il rivestimento aerospaziale è un rivestimento speciale applicato alla superficie dei veicoli spaziali aerospaziali. It has the characteristics of high temperature resistance, radiation resistance, oxidation resistance and corrosion resistance, which can protect the surface of aerospace spacecraft from the extreme environment encountered in high-altitude flight and extend its service life. Aerospace coatings have a wide range of applications, covering various parts of aircraft, satellites, rockets and other aerospace spacecraft, such as fuselage, engine, wing surface, eccetera.

Metodo di rilevamento
The following is a detailed description of the test method for the performance parameters to be tested for aerospace coatings:
Resistenza termica: Thermal stability and thermal decomposition characteristics of coatings at high temperatures are measured using a thermogravimetric analyzer.
Resistenza alla corrosione: Using salt spray test, corrosion test and other methods to simulate the corrosion resistance of aerospace spacecraft in different corrosive environments.
Radiation resistance: use X-ray irradiation test, proton irradiation test and other methods to simulate the radiation resistance performance of aerospace spacecraft in radiation environment.
Adesione: A peel test is used to measure the adhesion strength between the coating and the substrate.
Resistenza agli agenti atmosferici: use light aging test to simulate the weather resistance of aerospace spacecraft under different light and climate conditions.
Resistenza all'usura: The wear test is used to measure the wear degree and wear resistance of the coating under different wear conditions.
Resistenza ai graffi: The scratch test was used to measure the scratch degree and scratch resistance of the coating under different scratch conditions.
