Abstract:
      The technical process, formula and the operating step of the hard anodic oxidation of 7A04 aluminum alloy were presented. In order to meet the functionality, assembly, corrosion resistance, wear ability and appearance of the photoelectric aiming device, the thickness and the hardness of the oxidized film were strict restricted.
