| The work aims to achieve rapid verification of the adaptability of helicopters to polar atmosphere and solve the problem of difficult assessment inpolar atmosphere. The accelerated test environment spectrum of aluminum alloy was established according to the polar atmosphere, and the corrosion behavior of high strength aluminum alloy after accelerated test and outdoor exposure test was compared and analyzed by means of corrosion loss, scanning electron microscope and laser confocal microscope test. The corrosion rates of 2024 and 7075 aluminum alloys in polar atmosphere were 14.52 g/(m2.a) and 10.75 g/(m2.a), respectively, and the corrosion products were composed of AlOOH and Al2O3. Surface wetting time and deposition of salt particles are the main factors leading to corrosion of aluminum alloy, and the freeze-thaw cycle phenomenon accelerates the corrosion process. |
