Aerospace coating is a special coating applied to the surface of aerospace spacecraft. 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, atbp.

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

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

Paglaban sa kaagnasan: 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.

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

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

Paglaban sa pagsusuot: The wear test is used to measure the wear degree and wear resistance of the coating under different wear conditions.

Scratch resistance: The scratch test was used to measure the scratch degree and scratch resistance of the coating under different scratch conditions.
