Pitting corrosion is a type of corrosion that attacks a particular area of metal and eventually leads to the formation of holes in the metal.
Pitting corrosion occurs when the cathode (damaged coating) is large and the anode (exposed metal) is small.
This leads to a type of galvanic corrosion that begins at the surface of the metal but can spread downwards and eventually lead to the structural failure of the metal.
Damage Caused by Pitting Corrosion:
Pitting Corrosion can lead to the formation of pits on the surface of the metal.
The shape of these pits can vary from shallow and wide to deep and narrow.
