Comparison of accelerated and atmospheric exposure tests for corrosion of aluminum alloys

摘要

Two Al-Cu alloys (2024-T4 and 7075-T7351) and two Al-Li alloys (2091-T84 and 8090-T8171) were exposed for 2 years in a moderately aggressive marine environment, and their corrosion behaviour was compared with the in accelerated tests for intergranular corrosion (Air 9048 and MIL H-6088F) and exfoliation (ASTM G-34). Exfoliation tests using solutions modified by previous exposure to the test solution until a constant pH was obtained were also carried out with the two Al-Li alloys. Although the accelerated tests do produce the type of attack intended, the results in the aggressive exco solutions do not agree well with those from outdoor exposure, even using the modified solution.
