Document Summary
A direct chemical attack is an attack from a direct exposure of a bare surface to caustic liquid or gaseous agents. An electrochemical attack is comparable with electroplating, anodizing, or in a dry cell battery. Corrosion can be prevented by using alclad, anodizing, and alodizing: define the following forms of corrosion, oxidation a chemical reaction in which a metallic element is combined with oxygen, uniform surface unvaried corrosion across a surface. Salt, mercury, water, air, and organic growth: name at least ten areas where corrosion is likely to form an aircraft. The steps to treating aluminum alloy for corrosion are: mechanical corrosion removal all traces of corrosion must be removed as well, applied chemical neutralization , 5y. Chromac acid solution, after 5 minutes, wash off and apply alodine: apply protective coating, name the various protective coatings available for aluminum alloys.
