Abstract
Corrosion, which is commonly defined as the deterioration of a material (usually a metal) or its properties because of a reaction with its environment, is a global problem. NACE International, the Corrosion Society, estimates that global corrosion and its consequences cost developed nations about 3%–5% of GDP or GNP. Methods that are commonly employed to combat corrosion include cathodic protection, materials selection, coatings and linings, and corrosion inhibitors. In this chapter the basics in regard to corrosion are covered, including definition, cost and consequences of corrosion, types of corrosion, factors influencing corrosion, theories of corrosion, and mitigation approaches.
