The main functions of passivation
Improvement of corrosion resistance: The core purpose of passivation is to significantly reduce the rate of corrosion of metals by forming a thin and stable oxide or passivation film on the metal surface, which effectively isolates the metal from direct contact with corrosive substances in the external environment (such as moisture, oxygen and chemicals).
