Abstract：The 7xxx series aluminum alloy is widely used in manufacturing because of its light weight, high strength and easy processing. However, with the rapid development of modern science and technology, the performance requirements of aluminum alloy materials are increasingly stringent, especially in terms of corrosion resistance. Gradient nanostructure, as an innovative material design concept, achieves a synergistic enhancement of strength and toughness by carefully constructing gradual changed microstructure or composition within the material. Integrating this advanced structure into aluminum alloy materials opens up a new pathway to enhance the corrosion resistance of aluminum alloys, promoting technological innovation and progress in related industrial fields. This paper provides a detailed account of the preparation methods and performance achievements of gradient nanostructured aluminum alloys, especially focusing on the profound impact of gradient nanostructures on the corrosion resistance of 7xxx series aluminum alloys and its underlying mechanism. At the same time, the paper looks forward to the design of gradient nanostructured aluminum alloy materials in the future, providing new ideas for future research on improving the corrosion resistance of aluminum alloys.
