OVERVIEW OF CORROSION AND ITS CONTROL: A CRITICAL REVIEW

Abstract

Corrosion is the degradation of materials usually metal owing to chemical reaction with the environment which result in a functional failure of component. Corrosion is a reverse extractive metallurgy, which depends on the concentration of environment, stress, erosion and the temperature. It causes major economic losses ranges from 1% to 5% of GNP per year for any nations. In addition, corrosion not only increases the costs of component but it also responsible for life losses and safety hazard. Hence, the aim of this review paper is to provide an overview of distinct types of corrosion and their preventive method. So, that corrective action may be taken to minimize the effect of corrosion related problems.
