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 : |
New modern technologies require new innovative materials. Corrosion control of metals is an important activity of technical, economical, environmental, and aesthetic importance. The use of oxides, such as chromates, is highly effective in corrosion protection. Scientists are looking at alternative materials to replace environmentally hazardous materials, e.g., chromates. One of the group of materials identified as corrosion inhibiting are conducting polymers (CPs). CPs have acquired more attentions in the last decades due to their environmentally benign nature and high effectiveness to protect steels against corrosion. The conducting polymer such as Polyaniline, Polypyrrole,Polythiophene, Polycarbazole, Polyindole etc. work as a strong oxidant to the steel, inducing the potential shift to the noble direction. The strongly oxidative conducting polymer facilitates the steel to be passivated. The review paper presented below attempts to summarize extensive studies of Polyaniline, Polypyrrole and Polythiophene polymer and their anticorrosive properties. Several researchers have reported diverse views about corrosion protection by CPs and hence various mechanisms have been suggested to explain their anticorrosion properties. These include anodic protection, controlled inhibitor release as well as barrier protection mechanisms. Different approaches have been developed for the use of CPs in protective coatings (dopants, composites, blends). |
