Abstract : A study was performed comparing the Corrosion resistance of various aluminum alloys in shipboard environments with an accelerated laboratory corrosion test environment. An Al-Li access panel for the F/A-18 was also tested. For comparison 7075 aluminum alloys were tested in the exfoliation susceptible T651 and the resistant T7351 temper. Sulfur dioxide salt fog (ASTM G 85 A4-85) tests were conducted. The shipboard exposures were performed aboard aircraft carriers deployed to the Pacific Ocean, Persian Gulf and Indian Ocean during the monsoon season. The Al-Li alloys exhibited pitting corrosion similar to 7075 T7351.
