The mechanism can be explained by the thin film theory, that is, the passivation is caused by the action of metal and oxidation, and a very thin, compact, well-covered and firmly adsorbed passivation film is formed on the metal surface. This membrane exists independently, usually as a compound that oxidizes metals. It ACTS as a complete separation between the metal and the corrosive medium, preventing the metal from contacting with the corrosive medium, thus basically stopping the metal from dissolving and forming a blunt state to achieve the anti-corrosion effect.

Advantages of passivation

Compared with the traditional physical sealing method, the passivation treatment has the feature of absolutely not increasing the workpiece thickness and changing the color, which improves the precision and added value of the product and makes the operation more convenient.

Because the passivating process is carried out in a non-reactive state, passivating agent can be used repeatedly, so it has a longer life and is more economical.

Passivating promotes the formation of oxygen molecule structure passivating film on metal surface, which is compact, stable in performance and has self-repairing function in air at the same time. Therefore, compared with the traditional method of anti-rust oil, passivating film formed by passivating is more stable and more resistant to corrosion.
