Definition of corrosion - chemical and electrochemical corrosion. Reaction
between a metal surface and gases - oxidation, hydrogen influence, nitridation,
sulfidisation, carburisation, carbonyl corrosion. Consequences of corrosion -
technical, economical, accidents, cost and maintenance. Nature of the corrosion
reactions, corrosion products - passivity, transpassivity. Forms of corrosion -
general (uniform) localized, pitting and crevice corrosion, galvanic attack,
intergranular corrosion, knife-line attack, stress corrosion cracking, fatigue
corrosion, dealloying attack, exfoliation, fretting, erosion and cavitation.
Corrosion control - corrosion resistance materials, design modification,
application of coatings, change of environment, intervention in the reactions -
cathodic and anodic protections. Changes the procedures - start-up, shut-down,
inspection, monitoring, maintenance. Corrosion prevention - analysis and
diagnosis of damage - initiation of the corrosion control at the design stage
of the system.
