[0002] The most core purpose of anodic oxidation treatment is to enhance the corrosion resistance of molybdenum alloy, and through an electrochemical oxidation process, a dense oxide film is formed on the surface of the molybdenum alloy. The film can effectively isolate the metal matrix from the contact with the corrosive environment. The formed molybdenum oxide film has limited protection, but its density can be improved through process optimization to block the penetration of oxygen, moisture and corrosive media.

[0003] During the oxidation treatment of the molybdenum alloy plate, the clamp is used to clamp and limit the molybdenum alloy plate. The oxidation treatment degree is low at the contact position of the clamp and the molybdenum alloy plate. Since the clamp is always fixed at one place of the molybdenum alloy plate, the clamp will cause obstruction to the surface of the molybdenum alloy plate, resulting in incomplete oxidation treatment and affecting the product quality.
