Corrosion of metal is an electrochemical process. In the corrosion process, electrons flow from high energy areas of metal to low energy areas through a conducting solution on the surface of the metal. The solution is called an electrolyte, caused by water, rain, moisture, or humidity. Not very much of an electrolyte is needed to cause corrosion. Even *0% relative humidity will form an electrolyte, which can cause corrosion. The high energy area of a metal is called an anode. This is the area of metal where current leaves to enter an electrolyte. The low energy area is a cathode. Current leaves the electrolyte and returns to the metal at the cathode.
