“…It was in agreement with the results of EIS and M-S analysis. Owing to the temperature effect on the electronic properties of passive film, the similar result was obtained by Li 26 on the passive film on X80 pipeline steel, and the author attributed this behavior to the decrement of the film compaction with increasing temperature. The dependence of the electronic property on the formation temperature was related to charge neutrality in the film.…”

The electronic properties of passive film formed on nickel in bicarbonate/carbonate buffer solution were studied by electrochemical impedance spectra (EIS) and Mott-Schottky plot. The film composition was analyzed by X-ray photoelectron spectroscopy (XPS). The results showed that passive film exhibited p-type semi-conductive character, and the acceptor density (N A ) decreased with increasing potential, prolonging time, decreasing temperature, increasing pH value and decreasing chloride/sulfur ions concentration. The transfer resistance and film resistance increased with the above factors changing. XPS results showed that passive film was composed of NiO and a little amount of Ni 2 O 3 .

“…In order to fit the impedance spectra, an electrochemical equivalent circuit is provided in Figure 2d, 7 in which, R s is related to the solution resistance, Q 1 is the double layer capacitance, R 1 and R 2 correspond to the transfer resistance and film resistance, respectively. Q 2 is the film capacitance, and W represents the Warburg impedance.…”

“…Hamadou and co-workers 6 systematically studied the characterization of a passive film formed on low carbon steel in borate buffer solution by EIS, finding an n-type semi-conductive property of the passive film, and the donor density of passive film decreased with increasing formation time and potential. Our groups 7 have found that the corrosion protection effect of the passive film formed on carbon steel decreased with increasing temperature, adding chromium into the substrate and increasing chloride ion concentrations.…”

The joint effect of temperature and pH value on the corrosion behavior of X80 steel in carbonate/bicarbonate buffer solution was detected by cyclic voltammetry (CV), electrochemical impedance spectroscopy (EIS) and Mott-Schottky analysis. The results show that an unstable corrosion film will be formed on the X80 steel surface in low pH value solutions, and a better protective corrosion film can be formed on the X80 steel surface in high pH value solutions. On the whole, the corrosion film resistance and transfer resistance increase with the increment of pH value, and decrease with increase of solution temperature, which indicates that the protective effect of the corrosion film on X80 steel is enhanced with increasing pH value and decreasing the solution temperature. The corrosion film formed on X80 steel surface in carbonate/bicarbonate buffer solution has an n-type semi-conductive character, and the donor density decreases with increasing the pH value, and increases with increasing the solution temperature. The flat-band potential and pH value have a linear relationship with a positive slope.

Around the world, there are thousands of metal structures completely or partially buried in the soil. The main concern in their design is corrosion. Corrosion is a mechanism that degrades materials and causes structural failures in infrastructures, which can lead to severe effects on the environment and have direct impact on the population health. In addition, corrosion is extremely complex in the underground environment due to the variability of the local conditions. The problem is that there are many methods to its evaluation but none have been clearly established. In order to ensure the useful life of such structures, engineers usually consider an excess thickness that increases the economic cost of manufacturing and does not satisfy the principles of efficiency in the use of resources. In this paper, an extended revision of the existing methods to evaluate corrosion is carried out to optimize the design of buried steel structures according to their service life. Thus, they are classified into two categories depending on the information they provide: qualitative and quantitative methods. As a result, it is concluded that the most exhaustive methodologies for estimating soil corrosion are quantitative methods fed by non-electrochemical data based on experimental studies that measure the mass loss of structures.
