CET Corrosion - Forms of Corrosion

Nov 07, 2018 · The use of chemical-resistant protective coatings or more resistant materials will control these problems. While this is the most common form of corrosion, it is generally of little engineering significance, because structures will normally become unsightly and attract maintenance long before they become structurally affected.
