Resumo de testes de desempenho e métodos para revestimentos aeroespaciais

O revestimento aeroespacial é um revestimento especial aplicado à superfície de naves espaciais aeroespaciais. 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..

Método de detecção
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.

Corrosion resistance: 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.

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

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

Resistência ao desgaste: 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.

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

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

Diferença de cor: 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, e pode haver alguns padrões e especificações da indústria, for the performance testing of aerospace coatings, the corresponding test methods and standards should be selected according to the actual needs.
