Rusting, the formation of iron oxides, is a well-known example of electrochemical corrosion. In the most common use of the word, this means electrochemical oxidation of metal in reaction with an oxidant such as oxygen or sulfates.
Corrosion engineering is the field dedicated to controlling and preventing corrosion. It is the gradual destruction of materials (usually a metal) by chemical and/or electrochemical reaction with their environment. Corrosion on exposed metal, including a bolt and nutĬorrosion is a natural process that converts a refined metal into a more chemically stable form such as oxide, hydroxide, carbonate or sulfide.
