An Overview On the Protection Against Corrosion of Steels

In paper, mostly unknown problems of corrosion in the presence of mechanical strain and physical fields, as well as the problem of determining the stiffness characteristics of thin-film coatings and adhesive properties of the coating binder which are the barriers against corrosive wear, are considered. To assess the stiffness characteristics of the thin-walled circular samples with a complex structure, the experimentally-theoretical approach is used. There is also a designed experimental - theoretical method for determining the adhesion of coatings. It is noticed that there is an effect of the magnetic field for reducing the corrosive wear, and a new way to protect structures from corrosion is presented as well. Besides, active overlays that create local regions of compression are offered to reduce corrosion levels, as well as a protective coating with shells of complex geometry and a shielding membrane forming blowing film channels.
