Understanding Passivation Treatment
Passivation treatment is a crucial process in the manufacturing of metal components. It involves the use of chemical solutions to create a protective layer on the surface of the metal, which prevents corrosion and enhances its durability. The passivation treatment process is essential for stainless steel, which is highly susceptible to corrosion.

During the passivation treatment process, the metal surface is cleaned thoroughly to remove any impurities or contaminants that may interfere with the formation of the protective layer. The metal is then immersed in a chemical solution that contains nitric acid or citric acid, which creates a thin oxide layer on the surface of the metal. This oxide layer acts as a barrier between the metal and the environment, preventing any corrosive agents from penetrating the surface.
Passivation treatment is widely used in various industries, including aerospace, automotive, and medical devices. It is particularly important in medical devices, where the metal components come into contact with bodily fluids and must be free from contaminants that could cause harm to patients.
In conclusion, passivation treatment is a critical process in the manufacturing of metal components. It enhances the durability of metals and prevents corrosion, making it an essential step in various industries.
