“…• With respect to the CV experiments, quantifying the contribution of oxide layer to hydrogen adsorption will be useful in establishing the method for quantitative analysis. Certain experimental and computational methods such as Kelvin probe method [56] or Finite Element Analysis based hydrogen transport model [57] have been proposed for this very purpose. Ab initio calculations on the trapping of hydrogen by oxides can also provide valuable insights in this regard.…”

“…This Pd coating can be either prepared by electrodeposition process or PVD deposition. However, some authors [61][62][63] criticize that the procedure of Pd coating was usually not documented in the literature, and pointed out defective, porous Pd coating and Fe-Pd interface will trap more hydrogen and affect the permeation results obtained in Devanathan-Stachurski hydrogen permeation cell. In order to study the effect of the sample preparation process of PVD deposited Pd thin film layer on the permeation results obtained by hydrogen electrode method, a comparison of different PVD systems, substrates and surface roughness was performed.…”

Quantitative detection of hydrogen in metal is important in providing a better basis for fundamental investigations of hydrogen embrittlement and hydrogen-related corrosion phenomena. Thermal desorption spectroscopy (TDS) has long been used in characterizing different hydrogen traps inside materials. However, in TDS measurements, the diffusible hydrogen (hydrogen at interstitial sites and weakly bound hydrogen) is usually not detected. The Davanathan-Starchurski permeation technique can cover this shortage. However, for such experiments, the stability of the palladium at the exit side, i.e. in aqueous solution under high potential polarization is an important issue. Alternatively, a Kelvin probe-based (KP-based) potentiometric method developed a few years ago has shown to allow quantitative determination of hydrogen in metal. This method is based on measuring the hydrogen electrode potential on the Pd-coated surface. The aim of this work is to check the reliability of this method and to demonstrate its potential applications in determining the hydrogen amount distributed in both shallow and deep traps in steel. The results reveal that different crystallographic orientation, grain shapes and grain sizes of the deposited palladium film (in the range of variation in this work) do not cause relevant effects on the KP-based hydrogen detection. It is shown in this work that the time lag and permeation rate derived from the permeation curves obtained by this method show a very good reliability and the calculated hydrogen amount shows a good agreement with TDS results. 5 wt.% Ni ferritic steel is used as a model material in this work.

“…[11][12][13][14] However, the surface state should not be ignored as it is where the first contact occurs with a potential hydrogen-containing environment. This was emphasized through mathematical modelling of the electrochemical hydrogen-permeation in steel, 15,16 studied in a Devanathan-Stachurski setup. The results of the modelling-requiring the full (electro)chemical and physical description of the hydrogen reduction, ad/absorption, diffusion, trapping, desorption incl.…”

“…Casanova et al 21 indicated that the charge transfer occurred at the metal/oxide boundary. A circular mechanism of iron reduction/re-oxidation under anodic polarization was described by Vecchi et al 16 In this mechanism charge transfer occurred between atomic hydrogen and the oxide. This resulted in a partial reduction of the oxide followed by re-oxidation under the anodic polarization.…”

“…Yu et al 23 further corroborated the decrease in stability of the passive -film, showing that hydrogen permeation resulted in a decrease in the final static open circuit potential, the cathodic charge for reduction and the charge transfer resistance of the passive film. Vecchi et al 16 discussed the possibility of the net oxide reduction/re-oxidation effect not being zero in most cases, resulting in changes in the local chemistry of the oxide layer. This disparity on the stability of passive layers seems to have been a result of the differences in passivation conditions (time, electrolyte and material), [19][20][21]23 showing the importance of using controlled oxide layers in order to acquire reproducible results.…”

Most research on the hydrogen embrittlement of steel dealt with the interaction of hydrogen with the metal bulk microstructural features, whereas the first contact with hydrogen-containing environments occurs at the metal surface. Steel (when un-polarized) is always covered with an oxide layer, varying in composition and thickness. The impact of the oxide layer on the hydrogen transport is, however, not fully understood. This study focused on the effect of controlled pre-formed thermal oxide layers at the exit side on the hydrogen transport through the surface of SEA 1010 steel, considering two distinct thermally produced oxide types as test cases. Results demonstrated that thermal oxides can greatly limit hydrogen diffusion, with bilayers (hematite/magnetite) having a greater effect compared to magnetite layers. Increased oxide thickness resulted also in greater limiting diffusion. The main objective of this manuscript is to provide experimental evidence concerning the effect of oxide layers on the hydrogen transport through steel. Model thermal oxide layers were used to emphasize the importance of considering the surface characteristics when investigating hydrogen transport through metallic components.
