Abstract
This chapter provides an introduction to subsequent chapters. It presents corrosion engineering goals to reduce impact. It evaluates corrosion cost and significance for preventing catastrophic failure in bridges, nuclear facilities, airplane components, and equipment in chemical, petrochemical, transportation, and construction industries. It briefly explains corrosion initiation conditions, electrochemical polarization, and passivity to show a relationship with different corrosion types including uniform corrosion attack, galvanic corrosion, pitting, crevice corrosion, stress corrosion cracking, intergranular corrosion, filiform corrosion, and hydrogen damage. The chapter also describes corrosion rate determination techniques and corrosion rate calculation from corrosion current.
