Acier L'acier est un alliage métallique utilisé dans les domaines de la construction métallique et de la construction mécanique.
L'acier est constitué d'au moins deux éléments, le fer, très majoritaire, et le carbone, dans des proportions comprises entre 0,02 % et 2 % en masse1.
C'est essentiellement la teneur en carbone qui confère à l'alliage les propriétés du métal qu'on appelle "acier". Il existe d’autres métaux à base de fer qui ne sont pas des aciers comme les fontes et les ferronickels par exemple.

| Résumé : |
This article examines the four predominant sources of corrosion that occur “in the wild” and compares them to observational results found in exposure to accelerated corrosion conditions. By combining these observational attributes to mechanistic attributes previously examined, the use of accelerated corrosion testing can be better used as an indicator of how a coating will perform in various environmental conditions. |

- MECHANISMS OF CORROSION ON STEEL COATED WITH ORGANIC COATINGS : Anodic : Fe -> Fe++ + 2e (oxidation), Cathodic : 2H2O+O + 4e -> 4OH (reduction) - Fe + 2H+ -> Fe++ + H2
- CORROSION CAUSATION AND EFFECTS : Erosion-induced corrosion - Damage-induced corrosion - Conductive-pathway-induced corrosion - Contamination-induced corrosion
