The Relation of Water from Humid Atmospheres on the Corrosive Action of Foreign Deposits on Aluminum and its Alloys

摘要

It has been shown that pure water has little corrosive action on aluminum, a fact which is attributed to the formation of a protective film on the aluminum surface.n It has been shorn that in the presence of corrosive deposits, a critical humidity below which corrosion does not occur exists for aluminum as well as for iron, copper, or magnesium and is strongly dependent upon the properties of the deposit.
