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 : |
The coating materials which provide specific performance outcomes are called functional and specialty coatings. Application of functional coatings are becoming increasingly popular with the technology progress in material science field and continuous research in specialty coating segment. By using right functional/specialty coating, it is possible to achieve specific coating propergies like anti-corrosion, anti-corrosion, anti-erosion, anti-wear and chemical resistance, infra-red rejection, enhanced light transmission, electrical dissipation etc. Applications of these coatings are carried out over variety of substrates including but aluminum, glass etc. to deliver the special properties for which it is designed. |
