What Are the Surface Treatment Methods of Molybdenum Alloy?

The surface treatment methods of molybdenum alloy mainly include the following types:

Pickling treatment: use acidic solution to dissolve oxides and impurities on the surface of molybdenum alloy, make the surface clean, increase surface roughness and improve coating adhesion.

Electrochemical polishing treatment: A current is passed through the electrolyte to cause a redox reaction on the surface of the molybdenum alloy, remove surface oxides and impurities, and obtain a smooth surface.

Oxidation treatment: use high temperature oxidation or electrochemical oxidation to form an oxide film on the surface of molybdenum alloy to improve the surface corrosion resistance and ceramicization degree.

Passivation treatment: react the molybdenum alloy surface with chemical substances to form a passivation film to improve the corrosion resistance and electrochemical performance of the surface.

Electroplating treatment: A layer of metal or alloy is plated on the surface of the molybdenum alloy to make the surface bright and beautiful, and to improve the electrochemical performance of the molybdenum alloy.
