ABSTRACT
Since corrosion involves interaction between material and environment, the first approach to corrosion prevention is obviously the use of the most compatible material in a given environment and the next approach is to reduce the aggressiveness of the environment toward the material in use. Provision of a coating to separate the environment from the material in order to prevent their interaction is also a natural consideration, and many such coatings have been developed and are being used. Cathodic and anodic protection are preventive measures based on electrochemical principles of corrosion. Lastly, an improvement in design of the metallic component or the system to which it belongs can reduce corrosion in many cases.
