Research on the Influence of Anti-Corrosion Measures of Airborne Equipment on Electromagnetic Shielding Effectiveness
[Purpose/Meaning]To investigate the impact of anti-corrosion measures for airborne equipment on electromagnetic shielding effectiveness,[Methods]the study focuses on the anti-corrosion measures for fasteners,access panels,and electrical connectors of airborne equipment.By changing the frequency of the electromagnetic,the research explores the optimal anti-corrosion measures that affect electromagnetic shielding effectiveness.Additionally,the study employs wet heat tests,acidic salt fog tests,temperature and low pressure tests,and electromagnetic shielding performance tests to examine the anti-corrosion capabilities of several measures during the tests and the changes in electromagnetic shielding effectiveness the environmental tests progress.[Results/Conclusions]The results show that most anti-corrosion measures,when properly applied,do not affect electromagnetic shielding effectiveness while some measures pose a risk of leakage in high-frequency electromagnetic fields;after long-term environmental testing and corrosion aging,the shielding effectiveness decreases with the onset of corrosion.
