The formation of a strong contact layer in the “metal – paint layer” system is one of the important factors for the reliable operation of the protective coating. The development of methods for increasing adhesion and reducing defects at the boundary of metal surfaces with paint and varnish coating using nanoscale additives is the most effective way to obtain guaranteed quality characteristics. To this end, a number of different nano-additives have been studied in wide dosage ranges and the dependences of changes in the properties of coatings for a large set of operational impacts and factors have been determined. It is shown that the introduction of binary additives – carbon nanotubes and bismuth oxide – lead to a synergistic effect, expressed in increased adhesion, strength, hardness, water resistance, corrosion resistance and enhanced thermal stability of the contact layer. Thermomechanical and dielkometric studies of paint and varnish protective coatings with nano-additives have revealed patterns of changes in dielectric properties over time, which opens up opportunities for directional changes in all protection indicators. This approach allows us to consider the process of introducing nano-additives as a complex that contributes to obtaining the required parameters of quality indicators not only for protective coatings, but also for the formation of their specified service life under certain operating conditions.
