Why Metals experience Corrosion?
Corrosion can be defined as the destructive attack
of a metal through interaction with its environment.
Electrochemical corrosion is the most important
mechanism that causes Rust on Metal.
Four conditions must exist before electrochemical corrosion can proceed and metal rust:
(1) there must be something that rusts ,
the metal anode, where the oxydation reaction take places
(2) there must be a cathode, where the reduction reaction take
places
(3) there must be continuous conductive liquid path (electrolyte, usually
condensate and salt or other contaminations), for example:
water, seawater, condensing water, humidity..
(4) there must be a conductor to carry the flow of electrons from the anode to
the cathode.
