To ensure the long-term safe and reliable operation of aviation electronic equipment in the"three highs"marine environment,this paper studies the corrosion severity of five different simulated cabin sections in the tropical marine natural environment of Sanya.The corrosion rates of different parking areas and different cabin section environmental test pieces were compared and analyzed,as well as the characteristics of the corrosion environment factors and their quantity values.The results show that the outdoor environment has the highest salt fog deposition and corrosion severity,with the test pieces reaching the measurement limit(1 000 mg/m2)for salt fog deposition the most times,and the corrosion thickness is 261.8 μm.The platform enclosed cabin environment has the lowest corrosion severity,with the maximum salt fog deposition of the test pieces only 559.2 mg/m2,and the corrosion thickness is 5.3 μm.The severity of the corrosion environment is outdoor＞tidal enclosed cabin＞tidal semi-enclosed cabin＞platform semi-enclosed cabin＞platform enclosed cabin.This paper provides effective and reliable scientific theory and data support for the performance prediction and weather resistance analysis of aviation electronic equipment,and further analysis and research on the condensation behavior mechanism under different cabin section environments can be carried out in the future.
