Summary:With the rapid development of science and technology, wheel hubs of automobile are also developing towards lightweight and convenient. Aluminum alloys are increasingly used in wheel hubs due to their excellent performance, but the corrosion of aluminum alloy wheel hubs is still a big problem. This work briefly introduced several common corrosion types of aluminum alloy wheel hubs (filiform corrosion, pitting corrosion, grain boundary corrosion, stress corrosion, peeling corrosion). The influence of atmospheric environmental factors on the corrosion of aluminum alloy wheel hubs was introduced. Furthermore, the corrosion of different types of aluminum alloys in typical atmospheric environments at home and abroad, and the anti-corrosion methods of substrate modification and surface treatment for aluminum alloy wheel hubs were described.
