“…That is, hydrogen evolution may occur as part of cathode reactions (Reaction 7). Thus, many H atoms penetrate into the defect sites within the passive film, which increases film instability [58]. Therefore, more pits are produced as NaHSO 3 concentration increases.…”

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 .

For a hydrogenation heat exchanger operating under severe working conditions such as high temperature, high pressure and a hydrogen environment, perforation accidents caused by NH4Cl corrosion occur frequently. However, few reports on the effect of hydrogen on the corrosion behavior of metal materials in NH4Cl aqueous solution have been published. In this paper, X-ray photoelectron spectroscopy (XPS), electrochemical dynamic potential polarization, electrochemical impedance spectroscopy (EIS), Mott–Schottky (M-S) curves and scanning electron microscopy (SEM) were used to study the effect of electrochemical hydrogen charging (EHC) on the corrosion behavior of 321 stainless steel in an NH4Cl solution environment. The results show that: (1) hydrogen can change the structure and chemical composition of 321 stainless steel passive film and promote the conversion of metal oxide to hydroxide. At the same time, it can reduce the stability of the passive film. (2) Hydrogen can increase the thermodynamic and kinetic tendency of corrosion reaction and cooperate with Cl− to promote the occurrence of pitting corrosion.

“…After the EIS measurement, the APC was measured by scanning the potential from −5 mV (vs. open circuit potential, OCP) to 2.0 V (vs. OCP), with a scanning speed of 1 mV/s. The potential range for Mott‐Schottky measurements was from −1.0 V to 1.0 V. Test conditions were 20 mV/s scan rate, 5‐mV excitation voltage, and 1‐kHz constant frequency 37–39 …”

Titanium alloys are the best candidates to replace steels for drill pipes in horizontal wells. However, friction welding (FW) may significantly change the properties of titanium alloy drill pipes. In this work, the microstructure, tensile and impact mechanical properties, and corrosion fatigue performance of the FW zone were compared with those of the base alloy. The results show that the base material is mainly composed of equiaxed globular α (hcp)‐Ti, while the acicular α + β (bcc)‐Ti is dominant in the FW zone. Due to these differences in microstructure, the FW zone has higher strength but lower stiffness and toughness than the base alloy. In addition, the fatigue performance and corrosion resistance of the material decrease in drilling fluid. These results indicate that FW zones in titanium alloy drill pipes might be the weakest region where crack, fracture, and corrosion are more likely to occur.
