Design parameters and optimization of anodic protection systems

Anodic protection (A.P.) for corrosion control is based on the principle of protecting a metal or alloy from corrosion by raising the electrochemical potential of its surface to a value at which a protective oxide film (passive film) is formed and maintained. The principles of design of anodic protection systems are not very well developed. This paper discusses several important basic design concepts and describes several equations which can be used for the design and optimization of anodic protection systems for corrosion control.
