What is anodic protection

1.	What is anodic protection
Answer» Anodic protection (AP) is a technique to control the corrosion of a metal surface by making it the anode of an electrochemical cell > and controlling the electrode potential in a zone where the metal is passive .Anodic protection is used to protect metals that exhibit passivation in environments whereby the current density in the freely corroding state is significantly higher than the current density in the passive state over a wide range of potentials.
