Metal passivation is a process, as a result of which the surface of the metal is covered with a protective layer that makes the metal resistant to corrosion and other undesirable chemical and physical interactions.
During passivation, a thin layer of oxides, carbonates or other chemical compounds forms on the surface of the metal, depending on the type of metal and environmental conditions. This protective layer is usually more stable and less reactive than the metal surface itself, making the metal less susceptible to corrosion.
Passivation can be performed in various ways, depending on the type of metal and what kind of protection it requires. This can include immersing the metal in special chemical solutions, applying protective coatings or using electrochemical passivation methods.Note that this is not a permanent condition because any work on the metal in question can damage this layer, which means that another passivation will be necessary.
When the passive layer of the steel is damaged, for example by the welding process, it becomes necessary to re-protect it. Otherwise, the steel may lose its stainless properties and be susceptible to external influences. To perform re-passivation, it is necessary to carefully clean the affected area of the steel, removing any contaminants such as iron particles, scale oxides associated with the overheating process of the material, or operational dirt.
