The purpose of laser cleaning to remove the oxide film is to completely remove the anodic oxide film on the surface of the 7075 aluminum alloy substrate without damaging it. The wear resistance of the 7075 aluminum alloy substrate surface after laser cleaning is guaranteed to be no weaker than that of the original substrate, meeting the actual use of the material. Therefore, the influence of spot overlap rate on the surface quality and wear performance of the substrate after laser cleaning of the anodized film on the surface of aluminum alloy is studied.
