Gorbachova J. mechanism of corrosion of steel under corrosion-resistant coating and development of coal-epoxy coatings based on dehydrated coal tar

The object of research are corrosion-resistant coatings in particular, coal-epoxy coatings, and construction under corrosion-resistant coating;the purpose of scientific research are the development of concepts of the mechanism of corrosion of steel under corrosion-resistant coating and development of cheap corrosion-resistant coating, which have with high resistance to electro corrosion;these coatings must provide high durability of steel structures, which operate under conditions of constant flooding and stray current; research methods - in this paper we apply the standard, as well as specially existing and developed new physical-mechanical, the physical and physical-chemical methods and methods of research: determining relative viscosity, capacity, weight loss during heat treatment, adhesion, permeability of free-flow electro corrosion resistance , optical microscopy, infrared spectroscopy (IR), X-ray;scientific novelty the dissertation - developed concepts about the relationship between blocks and grains were due to single ion - electron contact-type PDE-Fe2 +-PDE, which determine its strength and corrosion resistance. It considered a relay mechanism of proton transfer through the coating, part of the lateral forces of repulsion in the separation of the cations Fe2 + from the edges of the grains of ferrite, under the pressure of a protective coating. There is improved method for determination of electrical corrosion protective coatings; sphere of use - protection against electric corrosion of metal structures for repair of culverts and overpasses.
