text: Some cases of electrochemical corrosion (mainly with cathodic reduction of oxygen) in natural mediums are characteristic—for example, atmospheric corrosion, which takes place in pure or polluted air in the presence of moisture sufficient for the formation of an electrolyte layer on the surface of the metal (particularly in the presence of corrosive gases such as sulfur dioxide, chlorine, or acid and salt aerosols); sea corrosion, which takes place upon the action of seawater; and underground corrosion, which occurs in soils.
