There are 6 main types of corrosion
Corrosion failures cost the world in excess of over $2 trillion dollars
Corrosion can result even in the absence of oxygen
Corrosion protection is best addressed in the design stage
Cathodic protection works to make the corrosion reaction thermodynamically unfavorable

Cathodic protection is an extremely powerful technology in that it has the power to almost completely stop corrosion on the structure it is deployed on. Most corrosion protection methods are passive in nature – such as paints. Cathodic protection is very much active. It attacks the corrosion problem at its heart.
