Le revêtement aérospatial est un revêtement spécial appliqué à la surface des engins spatiaux aérospatiaux. 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, etc..

Performance de détection
The performance testing of aerospace coatings needs to consider several factors to ensure that they meet the requirements and safety requirements of aerospace and spacecraft. The following is a detailed description of the performance parameters to be tested for aerospace coatings:

Méthode de détection
The following is a detailed description of the test method for the performance parameters to be tested for aerospace coatings:

Résistance thermique: Thermal stability and thermal decomposition characteristics of coatings at high temperatures are measured using a thermogravimetric analyzer.

Résistance à la corrosion: 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.

Adhésion: A peel test is used to measure the adhesion strength between the coating and the substrate.

Résistance aux intempéries: use light aging test to simulate the weather resistance of aerospace spacecraft under different light and climate conditions.

Résistance à l'usure: The wear test is used to measure the wear degree and wear resistance of the coating under different wear conditions.

Résistance à la rayure: The scratch test was used to measure the scratch degree and scratch resistance of the coating under different scratch conditions.

Résistance chimique: chemical immersion test is used to simulate the chemical resistance of spacecraft in different chemical environments.

Brillant: Use a gloss meter to measure the gloss of the coating and evaluate the gloss effect and gloss stability of the surface.

Différence de couleur: Use a color comparator to measure the color difference of the coating and evaluate its color consistency and accuracy.

We reminds you that different performance parameters may require different test methods and equipment, et il peut y avoir certaines normes et spécifications de l'industrie, for the performance testing of aerospace coatings, the corresponding test methods and standards should be selected according to the actual needs.
