“…It is evident that among the two-layer coating samples (Ti/Cr, Ti/Cu, Cr/Cu), Ti/Cr exhibits better corrosion resistance. The Ti/Cr coating has the largest capacitive arc radius and the highest low-frequency impedance of 46 940 Ωcm 2 , indicating its optimal corrosion resistance [37]. Ti is a metal with a strong passivation tendency and affinity for oxygen, forming a dense corrosion-resistant oxide film on its surface to protect it.…”

“…Figure 7 and table 1 present the potentiodynamic polarization curves and corresponding analysis results of the 316L substrate and all coated samples in a 3.5% NaCl solution. It is well known that the lower the corrosion potential (E corr ) is, the higher the corrosion tendency is [37]. The corrosion potentials of all coating materials are higher than that of the 316L stainless steel substrate (−0.282 V).…”

This article is based on the sacrificial anode cathodic protection principle and the optimization method of multilayer structure. According to the standard electrode potential of metals, starting from the corrosion-resistant passive film formed by the metal itself, Ti/Cr, Ti/Cu, Cr/Cu, and Ti/Cr/Cu coatings were prepared on a 316L stainless steel substrate using magnetron sputtering technology. The corrosion performance of the coatings was studied to explore the interaction patterns between them.The results showed that in artificial seawater, the Cr/Cu, Ti/Cu, and Ti/Cr metal bilayer film coatings exhibited an increasing impedance arc radius and widening phase angle plateau in the electrochemical impedance spectroscopy. In the polarization curve, the self-corrosion current, the self-corrosion potential and polarization resistance are all better than the substrate. In the static immersion test, the weight loss rate of the metal multi-layer film gradually decreased, with all samples showing a lower weight loss rate in the second week compared to the first week, ranging from 27% to 52%. By further designing the microstructure of the coating to mitigate the contradiction between hardness and toughness, and reduce the generation of pores, the corrosion performance of the new Ti/Cr/Cu coating is significantly improved. The coating can repair surface defects of the material, fill in micro and nano gaps, and enhance the cathodic protection effect of sacrificial anodes.

“…Given that hydrogen interacting with metal on the one hand facilitates the nucleation and development of defects in local volumes [6][7][8][9], and on the other hand accelerates its degradation due to the flooding ability of the media, which is caused by their electrochemical interaction with the metal and the release of hydrogen [10][11][12][13][14][15][16], this process is enhanced by a change in the stress-strain state in local volumes due to its change along the length of the pipe (bends, bends). All changes are most fully manifested on the inner surface of the pipe in contact with the environment, which affects the operational degradation that occurs under the combined action of stresses under the working pressure and corrosive-wetting environments, which reduces the material's resistance to strain and destruction.…”

In this study, a theoretical–experimental methodology for determining the stress–strain state in pipeline systems, taking into account the hydrogen environment, was developed. A complex of theoretical and experimental studies was conducted to determine the specific energy of destruction as an invariant characteristic of the material’s resistance to strain at different hydrogen concentrations. The technique is based on the construction of complete diagrams of the destruction of the material based on the determination of true strains and stresses in the local volume using the method involving the optical–digital correlation of speckle images. A complex of research was carried out, and true diagrams of material destruction were constructed, depending on the previous elastic–plastic strain and the action of the hydrogen environment. The change in the concentration of hydrogen absorbed by the material was estimated, depending on the value of the specific energy of destruction. A study was conducted on tubular samples, and the degree of damage to the material of the inner wall under the action of hydrogen and stress from the internal pressure was evaluated according to the change in specific energy, depending on the value of the true strain established with the help of an optical–digital correlator on the outer surface, and the degree of damage was determined. It has been established that the specific fracture energy of 17G1S steel decreases by 70–90% under the influence of hydrogen. The effect of the change in the amount of strain energy on the thickness of the pipe wall is illustrated.
