Anti-corrosion

Anti-corrosion refers to the protection of metal surfaces from corroding in high-risk (corrosive) environments.

When metallic materials are put into corrosive environments, they tend to have chemical reactions with the air and/or water. The effects of corrosion become evident on the surfaces of these materials. For example, after putting the iron into a corrosive atmosphere for an extended period, the iron starts rusting due to oxygen interaction with water on the iron's surface.
