The surface treatments of molybdenum electrodes can vary according to specific application needs. The following are some common molybdenum electrode surface treatments:
Pickling: Pickling with an acidic solution (such as nitric acid, sulfuric acid, etc.) can remove oxides and impurities on the surface and improve the purity and smoothness of the surface.
Mechanical polishing: Through mechanical grinding and polishing, surface roughness and blemishes can be removed, and surface smoothness and smoothness can be improved.
Passivation treatment: Treat the surface of the molybdenum electrode with a passivation agent (such as sodium nitrate, sodium sulfate, etc.), which can form a protective oxide film and improve oxidation resistance and corrosion resistance.
Electrochemical polishing: through electrochemical methods, polishing in a suitable electrolyte can obtain a smoother and smoother surface.
Covering coating: A protective coating, such as zirconium dioxide and silicon nitride, can be coated on the surface of molybdenum electrodes to enhance wear resistance and corrosion resistance.
