If the Ionic or Electro-chemical theory of corrosion, as described in the preceding chapter, be accepted it is then easy to divide all practical cases of corrosion into three types : (1) Auto Corrosion, (2) Contact Corrosion, and (3) Externally Induced Corrosion. (reference).
Corrosion is the chemical or electrochemical reaction between a material, usually a metal, and its environment that produces a deterioration of the metal and its properties.A chemist would classify corrosion as an oxidation, an electron-transfer reaction involving the loss of electrons. Metal Corrosion or Metallic Corrosion can be defined as the destructive attack of a metal through interaction with its environment. The most common example is Rust, an â¦ iron oxide Fe2O3, that is the consequence of the Corrosion process of Iron. + 9 others found this useful.
