“…From Fig. 11(a), it can be observed that the hydrogen oxidation current incrementally increases after a certain time lag corresponding to the hydrogen travelling time across the steel when the sliding was started which means that hydrogen was evolved as soon as friction was commenced [24]. It indicates that oxidation current increase occurs as a result of higher hydrogen diffusion and chemical reactions at the interface due to friction rubbing.…”

“…Turnbull et al [23] reported that addition of H 2 S and decreasing pH in entry electrolyte would increase the hydrogen entry. Tsuru et al [24] modified a DS set-up to study the mechanism of hydrogen entry into the steel during an atmospheric corrosion process and the effect of the steel passive layer and surface pH on the permeation rate. Ootsuka et al [25] later used the developed technique by Tsuru et al [24] in order to do online monitoring of hydrogen absorption into steel parts of a vehicle.…”

“…At this time, on the surface of the steels, hydrogen evolution reaction can be evolved as one of the cathodic reactions. According to the reports by some researchers, [1][2][3][4][5] in atmospheric corrosion, H atoms can be absorbed into steels during the corrosion in the atmospheric environments. For example, if the concentration of absorbed H atoms reaches in the order of sub ppm, 1 000 MPa-class steels may be susceptible to hydrogen embrittlement.…”

In this paper, hydrogen absorption behavior into iron was investigated by measuring alternating current responses for hydrogen-entry side and hydrogen-withdrawal side in an electrochemical hydrogen permeation cell. Hydrogen absorption efficiency of iron was evaluated as a function of electrode potentials by using both DC and AC components of the current responses. The hydrogen absorption efficiency of iron increased with decreasing cathodic polarization. Furthermore, frequency response characteristics of the hydrogen absorption efficiency were investigated at various polarization potentials and the results indicated that the hydrogen absorption efficiency decreased with increasing frequency of the perturbation potential. The frequency response characteristics of the hydrogen absorption efficiency was also simulated by using Fick's second law and the results suggested that hydrogen absorption kinetics can be considered to be faster than diffusion of hydrogen atoms in iron and to be under an equilibrium condition. By analyzing AC responses for hydrogen-entry side and hydrogen-withdrawal side, hydrogen absorption behavior into iron can be successfully evaluated.

Research on hydrogen embrittlement (delayed fracture) susceptibility of high strength steel bolts was reviewed from the viewpoint of metallurgical factors enhancing the resistance to delayed fracture, assessment of delayed fracture susceptibility based on the hydrogen absorption from atmospheric environments, and the mechanism of hydrogen entry into steel under atmospheric exposure.Resistance to delayed fracture was quantified based on the threshold hydrogen concentration Cth by means of laboratory constant load tests under cathodic hydrogen charging. Vanadium containing antidelayed fracture steel bolts had higher Cth values than conventional steel bolts, and showed good resistance to delayed fracture at tensile strength levels of 1 400 MPa under actual atmospheric exposure.Susceptibility to delayed fracture was evaluated by comparing Cth to absorbed hydrogen concentration C0 into steel bolts under atmospheric exposure. The good resistance to delayed fracture of Vanadium steel high strength bolts was attributable to sufficiently higher Cth than C0. Hydrogen permeation experiments under atmospheric exposure enabled more exact measurements of sub-surface hydrogen concentration into steel. Hydrogen permeability under atmospheric exposure showed a strong dependence on the time of the day, seasons and exposure locations.Mechanism of hydrogen entry was investigated by hydrogen permeation measurements under laboratory wet-dry cyclic conditions. Dominant factors that control hydrogen entry were temperature, relative humidity, and the amount of sea salt on the steel surface. Dependence of hydrogen permeability under actual atmospheric environments on daily temperature-humidity cycle, season and locations were explainable based on the effect of temperature, humidity and sea salts.KEY WORDS: hydrogen entry; delayed fracture; high strength steel bolts; hydrogen permeation; atmospheric exposure.
