Introduction
1. Background of standard formulation and analysis of technological evolution
With the rapid development of aerospace technology, special non-metallic materials are increasingly used in spacecraft. In order to ensure the functionality and reliability of the surface coatings of these materials, GB/T 43763-2024 "Special non-metallic material metal coatings for aerospace functional coatings" came into being. This standard aims to standardize the technical requirements, test methods and inspection rules of the coatings, and provide reliable quality assurance for the manufacture and use of spacecraft.
2. Comparison of standard frameworks
| Standard dimensions | GB/T 43763—2024 | Comparison with international standards | Comparison with industry standards |
|---|---|---|---|
| Scope | Surface coatings of special non-metallic materials such as polyetheretherketone (PEEK), polyphenylene sulfide (PPS), and polyimide (PI) | Coating requirements for similar materials in NASA standards | Comparison with MIL-STD-XXXXX military standards |
| Technical requirements | Including specific indicators such as coating structure, appearance, thickness, and adhesion strength | Technical details of EU aerospace standards | Analysis of differences with other domestic industry standards |
| Test methods | Microscopy, X-ray spectroscopy, thermal shock test, etc. | Comparison of international general test methods | Compatibility analysis of domestic standards |
3. Implementation suggestions
Production link:Strictly control the pre-treatment process of the coating to ensure that the surface of special non-metallic materials is clean and pollution-free.
Inspection link:Carry out full inspection or sampling inspection according to standard requirements, focusing on the test of coating thickness and adhesion strength.
Use and maintenance:Avoid the influence of environmental factors on the coating during storage, and pay attention to prevent mechanical damage and corrosion during use.
