Chapter 1 - Introduction to Corrosion

Abstract

This chapter describes corrosion. The term “corrosion” now encompasses all types of natural and man-made materials, including biomaterials and nanomaterials, and it is not confined to metals and alloys alone. The chapter also discusses the historical background of corrosion. Corrosion cannot be defined without a reference to environment. All environments are corrosive to some degree. The chapter discusses the consequences and costs of corrosion. Corrosion has a serious impact on defense equipment. The petroleum, chemical, petrochemical, construction, manufacturing, pulp and paper, and transportation (railroad, automotive, and aerospace) industries are the largest contributors to corrosion expenditure. The cost of corrosion differs from country to country..Corrosion engineering is the application of principles evolved from corrosion science to minimize or prevent corrosion. Corrosion engineering involves designing of corrosion-prevention schemes and implementation of specific codes and practices. Corrosion may severely affect the functions of metals, plants, and equipment. The chapter also discusses the health hazard involved with corroded structures.
