Molybdenum electrodes often require special surface treatments to meet specific application requirements. Here are some common surface treatments:
Pickling: By immersing the molybdenum electrode in an acidic solution, oxides and impurities on the surface can be removed, and the purity and surface quality of the electrode can be improved.
Mechanical polishing: Using mechanical grinding and polishing technology, the unevenness and roughness of the molybdenum electrode surface can be removed, and the surface finish can be improved.
Passivation treatment: passivation treatment is a surface chemical treatment method, which improves its corrosion resistance by forming an oxide film on the surface of molybdenum electrodes.
PVD coating: Using Physical Vapor Deposition (PVD) technology, a layer of ceramic or metal film is coated on the surface of the molybdenum electrode to improve its wear resistance, corrosion resistance or electrical conductivity.
