Experiments on the Protection of Steel and Aluminum exposed to Sea Water. Gives results of tests of various coatings and pigments. Fifty-four steel plates and thirty aluminum plates coated with various paints and enamels were immersed in sea water for six months, then removed and their condition investigated. The results are given in detail by A. H. Sabin, who in conclusion states with reference to the aluminum plates: The more nearly pure the aluminum the less it seems to need protection. The series which contain large amounts of copper or zinc are the most difficult to protect; corrosion seems to progress rapidly where the sea water gets the slightest admission, and it throws off the coating no matter how impervious the latter may be."
