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).
Answer 1: oxygen and carbon in the air :-). Answer 2: Depends on what type of corrosion you are referring to. Rust and corrosion are typically used interchangeably. Rust is one type of corrosion.Corrosion is essentially the disintegration of a engineered material. Rust is a chemical reaction, but there are other chemical reactions that cause corrosion of steel (typically acids).Other types of corrosion include fretting, erosion, cavitation, and galvanic reactions. There are many methods to prevent corrosion.nswer 1: oxygen and carbon in the air :-). Answer 2: Depends on what type of corrosion you are referring to.
