Metal passivation is a processby which the surface of the metal is covered with a protective layer that renders the metal resistant to corrosion as well as other undesirable chemical and physical interactions.
During passivation, a thin layer of oxides, carbonates, or other chemical compounds forms on the metal surface, depending on the type of metal and environmental conditions. This protective layer is usually more stable and less reactive than the bare metal surface itself, which significantly reduces the susceptibility of the metal to corrosion.
Passivation can be carried out in various ways, depending on the type of metal and the level of protection required. It may involve immersing the metal in specialized chemical solutions, applying protective coatings, or utilizing electrochemical passivation methods. It’s important to note that this is not a permanent state — any further processing or mechanical work on the metal may damage this layer, which means passivation must be repeated.
When the passive layer of the steel is damaged — for example, as a result of welding — it must be re-established. Otherwise, the steel may lose its stainless properties and become vulnerable to external elements. To perform repassivation, the affected area must be thoroughly cleaned to remove any contaminants, such as iron particles, scale oxides related to the overheating of the material, or other debris.
