“…Based on the molar concentrations distribution of Cu and Fe of the samples at different diffusion annealing temperatures, as shown in Figure 6, and considering that the molar volume of the samples did not change much during diffusion annealing process, the den Broeder method was used to calculate the diffusion coefficient of Cu in low-carbon steel for different temperatures [30]. The calculation formula is shown as Equation (2).…”

The effective diffusion of Cu in Fe is the key to forming a stable transition layer between copper and low-carbon steel, but it is seriously affected by several factors, especially temperature, and the diffusion of Cu can only be completed at high temperatures. In order to analyze the diffusion coefficient of Cu in low-carbon steel under high temperatures, and to obtain the best diffusion temperature range of Cu in steel, the electrodeposition method was used to prepare the diffusion couple of copper and low-carbon steel, which would be annealed under different temperatures for 6 h; meanwhile, the MD models were also used to analyze the diffusion behavior of Cu in Fe at different temperatures. The results show that the diffusion of Cu in low-carbon steel could be realized by high-temperature annealing, and as the temperature increases, the thickness of the Cu/low-carbon steel transition layer shows an increasing trend. When the annealing temperature is between 900 °C and 1000 °C, the thickness of the transition layer increases the fastest. The results of the MD models show that, when the temperature is in the phase transition zone, the main restrictive link for the diffusion of Cu in Fe is the phase transition process of Fe; additionally, when the temperature is higher, the main restrictive link for the diffusion of Cu in Fe is the activity of the atom.

“…However, when it is exposed to the air, Fe, the main component of steel, easily reacts with oxygen to form iron oxides, resulting in corrosion of the surface of the steel. Especially in humid environment, the presence of H 2 O promotes the formation of Fe(OH) 3 , and accelerates the corrosion [1][2][3].…”

“…[ 9,10 ] Usually, the O 2 could accelerate the corrosion by promoting cathodic reactions and influence the structure of corrosion products. [ 11–15 ] Furthermore, the critical crevice solution theory has elucidated the basic role of O 2 during the CC. [ 16,17 ] The O 2 is progressively depleted inside the crevice due to the restricted mass transport to the occluded site, which results in the separation of anode and cathode.…”

The crevice corrosion behavior of N80 carbon steel in acidic NaCl solution: The effect of O₂

The effect of O2 on crevice corrosion of N80 carbon steel in acidic NaCl solution is investigated. Crevice corrosion of N80 carbon steel could be initiated with or without O2 in acidic NaCl solution. A deep corrosion groove could be formed near the crevice mouth after crevice corrosion. The crevice corrosion of N80 carbon steel is ascribed to the increased pH inside the crevice in acidic NaCl solution. The presence of O2 in the solution could enhance the cathodic reaction processes outside the crevice, but it is not significant for the cathodic reaction processes inside the crevice. The galvanic corrosion effect between inner and outer steels could be enhanced by O2 and then promote crevice corrosion.

The corrosion product competition and transformation process of J55 under an O2/CO2 environment in the temperature range of 50–350°C and 0–1 MPa oxygen partial pressure range, respectively, were studied using electrochemical and surface analysis techniques as well as thermodynamic calculations to determine its corrosion rate change law and pitting corrosion phenomenon. This study demonstrates that the uniform corrosion rate of J55 with increasing temperature shows a trend of first increasing, then decreasing, and finally increasing. The transformation of its corrosion products, from FeCO3 into Fe3O4, is consistent with the altering corrosion rate law with increasing temperatures. J55 corrodes faster at 350°C as the O2 partial pressure increases. When the O2 partial pressure is low, the predominant kind of corrosion product that is obtained is FeCO3; when the O2 partial pressure exceeds 0.2 MPa, all corrosion products are transformed into iron oxides. As the oxygen partial pressure increases, J55's corrosion product film becomes increasingly less protective of the substrate, making the substance more vulnerable to corrosion reactions.
