| Abstract: |
| Aiming at the problem that the corrosion failure rate of airborne electronic equipment in the marine atmospheric environment of the South China Sea is obviously increased, this paper systematically analyzed the material system, external field failure phenomenon and corrosion mechanism of airborne electronic equipment in active aircraft. The results showed that the micro-corrosion of electronic equipment and its components had a great impact on its functional performance. The three-proof design of aircraft electronic equipment in service can not meet the harsh environmental adaptability requirements of the South China Sea. Key technologies such as integrated environmental accelerated test technology, micro-corrosion mechanism and the corresponding relationship between electrical signal transmission and corrosion are the key research in the future. Finally, combined with the causes and characteristics of corrosion, the specific corrosion protection countermeasures for airplane were given. |
