Schematic circulation system of synthetic seawater for fatigue test It has been recognized that the fatigue strength of steel in a corrosion environment is significantly affected by the fatigue loading speed.
That means that other factors, for example, the formation of the rust, electrocoating, stress concentration of the pit at the tip of the crack, corrosive dissolution etc. are thought to be related to the crack propagation behavior in seawater condition.

A significant part of such structures operates in a complex stress state when exposed to natural and technological environments that cause irreversible physical and chemical changes in the properties of materials.
As the analysis of the scientific literature shows, this is objectively due to the complexity of the metal-protective coating system, the versatility of physical and chemical processes and the influence of various factors on these systems in penetrating media, and insufficient studies of some stages and processes of their interaction.
Most researchers proceed from the concept that a coating film does not affect the mechanism of metal corrosion, but affects only the kinetics of the process, acting as a diffusion barrier.
Protection of metal against corrosion by paint and varnish, as well as by polymer coatings is determined by the following factors: mechanical insulation of the metal from the corrosive environment; adhesion preventing the formation of a new phase (rust) at the metal-coating interface; by slowing down electrode reactions causing the corrosion process by creating conditions for metal passivation; by structural transformations in the films that determine the properties of the coatings.
The composition of AKS-K is effective both in moderately aggressive and highly aggressive environments, and the composition of AKS-B shows protective properties only in moderately aggressive environments • The protective properties of coatings from the developed compositions are not much dependent on their thickness, which allows to apply one-layer coating under careful drying and degreasing the surface of metal structures; • coatings of the compositions AKS-K and AKS-B, applied over rust, significantly surpass the standard coating systems by the protective properties; • a characteristic feature of coatings from AKS-B is that they retain their protective properties in a highly aggressive environment when applied onto a rusty surface, while, when applied onto a clean surface, these coatings are completely destroyed after 7-8 cycles.
