* Wheathered steel has protection against atmospheric corrosion
by oxidation of an outer layer, called patina.
George: Regarding applications, heavier gold is most often specified where there is a possibility of atmospheric corrosion
A common type of gradual corrosion is oxidation, also known as atmospheric corrosion
. Whenever a metal is exposed to a gas that contains oxygen atoms along with atmospheric moisture, a reaction occurs.
This effectively stops atmospheric corrosion
of coastal tankage and other petrochemical assets.

of steel," Corrosion Science, vol.
In the hydrodesulfurization process, these heat exchangers can suffer deterioration from atmospheric corrosion
(externally, when the coating cannot completely protect the external surface) and by ammonium bisulfide corrosion (internally, when ammonium salts are formed) [5-7].

of steel," British Corrosion Journal, vol.
However, this impact results in potential wear at the interface, with a further risk of atmospheric corrosion
. A design modification was agreed involving the application of a nickel chrome electrolytic protective treatment.

"Effects of environmental factors on atmospheric corrosion
of aluminium and its alloys under constant dew point conditions".
Laboratory exposure of metals to synthetic environments containing S[O.sub.2] and/or N[O.sub.2] with humidified air has been used by different research groups for the investigation of the atmospheric corrosion
of metals and proved to be reliable [28-31].
