“…6. The H r form is characterized by a firmer bond with metal than the H s form what corresponds well to the results reported in [15,16]. Simultaneously, the bond energy of the H r form increases with increasing q (for instance, at the anodic polarization) faster than the energy of the H s form.…”

“…An increase of the initial water concentration in the ethylene glycol solutions up to 2 wt% causes an essential modification of a character of the solvation effects without a change of the nature of the HER rds in the presence of both Na 2 HAsO 4 [16] and (NH 2 ) 2 CS [15]. With increasing the initial water concentration up to 2 wt% both the solvated forms of the protons (C 2 H 4 (OH) 2 The hydrogen overvoltage increase was determined by the independent and direct polarization measurements with use of the equilibrium hydrogen electrode in the same solution as a reference electrode [11,17,18].…”

“…Chatzidouros et al (2011) used in-situ electrochemical hydrogenation to study the effect of hydrogen on the fracture properties of the heat-affected zone of pipeline steel. Tsygankova et al (2004) investigated the relationship between hydrogen evolution on the metal surface and hydrogen diffusion in the metal using electrochemical hydrogenation method. Barnoush and Vehoff (2010) found that the effect of hydrogen on the micro-mechanical properties of the material was due to the reduction of the load required to promote the release of dislocations, using electrochemical hydrogenation and nanoindentation experiments.…”

Purpose Alternating current (AC) corrosion is a type of corrosion that occurs in buried pipelines under AC stray current interference, which can increase the hydrogen embrittlement sensitivity of pipelines. However, rare research works have been conducted on the hydrogen permeability characteristics of pipeline steel under AC stray current interference. The purpose of this paper is to study hydrogen permeation behavior of X80 steel under AC stray current interference. Design/methodology/approach In this paper, the hydrogen permeation behavior of X80 steel under AC interference is studied by AC hydrogen charging experiment in a dual electrolytic cell. The relationship between hydrogen evolution rate and hydrogen permeation flux is studied using the gas collection method. The difference between AC hydrogen permeability and direct current (DC) hydrogen permeability is also discussed. Findings The anodic dissolution caused by AC corrosion promotes the chemical desorption reaction of the adsorbed hydrogen atoms on the surface, reducing the hydrogen atom absorption ratio by 70%. When the AC is smaller than 150░ A/m2, the hydrogen permeation process is controlled by the hydrogen atom generation rate, and the hydrogen permeation flux increases with the increase in hydrogen atom generation rate. When the AC exceeds 400░ A/m2, the hydrogen permeation process is controlled by the absorption ratio. The hydrogen permeation flux decreases with the decrease in the absorption ratio. Under AC interference, there is a maximum hydrogen permeation flux that linearly correlates to the H+ concentration in the solutions. Originality/value The high-strength steel is very sensitive to hydrogen embrittlement, and X80 steel has been widely used in oil and gas pipelines. To date, no research has been conducted on the hydrogen permeation behavior of pipeline steel under AC interference, and the hydrogen permeability characteristics of pipeline steel under AC interference are not clear. The research results of this paper are of great significance for ensuring the intrinsic safety of high-strength pipelines under AC stray current interference.

Hydrogen absorption into steel membrane was studied using an electrochemical hydrogen permeation technique. The investigations were conducted in the H 2 SO 4 + Na 2 SO 4 solutions with the constant ionic strength equal to 1 and pH equal to 1.80 and 1.13. The influence of CNS -anions has been studied. The Iyer, Pickering, Zamanzadeh (IPZ) analysis of the measured steady-state hydrogen permeation rates gives the rate constants of the steps of the HER, hydrogen surface coverage Ө H , exchange current density, i o , and kinetic-diffusion constant. The kinetic parameters of the HER have been estimated at a constant potential and a constant hydrogen overpotential. These data testify about the Volmer rate determining step (rds) in the HER.
