Protection of metal surfaces in contact with liquids
The SEQUION® have the property of forming films or protective Barriers between the metal surface and the corrosive medium and are chosen for different applications based on the protected area( anode or cathode), the type of film and the type of bond they have with metal.
The protective film formed by SEQUION® may be due:
- To an insolubilization of the inhibitor on the surface
- To a passivation of the metal surface
- To an adsorption of the inhibitor on the surface through the free electron pairs of some donor atoms (N,S,O,P):
N:->Fe° O:->Fe° S:->Fe°
