“…The change in C D , on the other hand, decreases with NaCl solution concentration and increases with temperature. This phenomenon has also been confirmed by other investigations (Grahame, 1957; Qin et al , 2021; Zhang et al , 2005; Pan et al , 2022). Although increasing the concentration of NaCl solution and temperature accelerates corrosion, the difference between the variation trend of C D under these two groups of experiments reflects distinct changes.…”

Purpose The relation between metal corrosion behavior and double-layer capacity remains unclear. This study aims to put forward a novel method to measure double-layer capacity. Design/methodology/approach A novel model based on generalized Frumkin–Butler–Volmer equation was put forward. Combining this model with potentiodynamic polarization test and electrochemical impedance spectroscopy, the structure of double-layer capacity can be characterized. Findings This study found that the corrosion rate of iron increased with NaCl solution concentration and temperature at the experimental range, but an essential difference existed. The capacity of the diffuse layer and Stern layer increased with temperature and decreased with NaCl solution concentration. The ratio of diffuse layer capacity and Stern layer capacity influences the corrosion rate directly, which can be regarded as one of the judging criteria for corrosion resistance of metal materials. Originality/value The convenient means of double-layer structure characterization is still blank. With this method, the corrosion behavior of metal materials can be further analyzed, especially in high-temperature and pressure environments.

“…R s refers to the resistance of the solution, R pore represents the resistance of the pore fluid in the corrosion product film (CPF), R ct is the charge transfer resistance. Q f and Q dl represent the constant phase elements of the CPF and double-layer (Pan et al ., 2022a, 2022b; Xi, 2023), respectively, which are used to replace ideal capacitors. The impedance fitting result coincides with the curve.…”

Purpose The purpose of this paper is to develop new types of anchor bolt materials by adding corrosion-resistant elements for alloying and microstructure regulation. Design/methodology/approach Three new anchor bolt materials were designed around the 1Ni system. The stress corrosion cracking resistance of the new materials was characterized by microstructure observation, electrochemical testing and slow strain rate tensile testing. Findings The strength of the new anchor bolt materials has been improved, and the stress corrosion sensitivity has been reduced. The addition of Nb makes the material exhibit excellent stress corrosion resistance under –1,200 mV conditions, but the expected results were not achieved when Nb and Sb were coupled. Originality/value The new anchor bolt materials designed around 1Ni have excellent stress corrosion resistance, which is the development direction of future materials. Nb allows the material to retain its ability to extend in hydrogen-evolution environments.

“…The produced H 2 diminishes the bonding force between the passivated film and the matrix, inducing a certain internal pressure. As a result, the defects within the film increase, and its thickness thins, which facilitates the rupture of the film [25,62,63]. The influence of imposed AC on the corrosion behaviour of the HEA can be reflected by Figure 8(a).…”

The corrosion behavior and mechanism of CoCrFeNi HEA under AC application were systematically studied in 3.5 wt.% NaCl solution containing different concentrations of NaHSO 3 . The results showed that the existence of HSO 3 − increased the defect density within the passivation film on the surface of the HEA. With the increase of HSO 3 − concentration, the passivation zone became narrow, E p shifted negatively, and i p increased, which indicated that the corrosion resistance of the HEA was weakened. When the HSO 3 − concentration increased to 0.1 M, a clear transition zone appeared, indicating that the increase in concentration reduced the passivity of the HEA, and its corrosion behavior changed from the typical passivation characteristic to the activation state with increasing i AC . The imposed AC promoted the nucleation of metastable pitting, which was indicated by a remarkable increase in the average pitting number density (N avg ) from 5 to 17 mm −2 with the enhancement of i AC .
