Aluminum alloys are extensively used in civil aircraft due to their lightweight, high strength, and excellent formability. However, their susceptibility to corrosion and corrosion fatigue poses a significant maintenance challenge in aviation environments. This study explores the effec-tiveness of ultrasonic nanocrystal surface modification (UNSM) technology in enhancing the corro-sion fatigue strength of Al7075-T6 alloy. Specimens were subjected to controlled corrosion condi-tions and treated with UNSM either before or after corrosion exposure. Corrosion fatigue tests re-vealed that UNSM treatment significantly increased fatigue life—by over 140 times compared to untreated corroded specimens—by inducing deep compressive residual stress, increasing surface hardness, and refining surface structure. These results highlight UNSM's potential to delay crack initiation and propagation in corrosive environments, offering a promising surface enhancement strategy for aircraft aluminum alloys.
