Abstract
In this chapter, we have discussed the basic principles of corrosion, factors affecting corrosion, effect of corrosion, types of corrosion, mechanism of corrosion, how to control corrosion, anodic and cathodic coating. This chapter enables the student to learn the fundamentals of corrosion and its effects, disadvantages of corrosion. Corrosion is the process of deterioration of metals as well as alloys in the presence of an electrochemical or chemical environment. It is an irreversible chemical reaction that results in the dissolution of the material. It also deals with the small visual change to complete failure of giant technical systems and causes a big blow to the economy and even hazard to people.
