During the cathodic hydrogen charging, hydrogen can be formed at the cathodically polarized electrode due to the applied potential. Further, depending on the medium, an additional material degradation and the associated formation of hydrogen can occur. It should be noted that the sample is … Meer weergeven During the immersion test, the amount of hydrogen absorbed depends primarily on the corrosion attack on the sample and subsequently on the presence of hydrogen poisons. The results of the aging tests can be seen in … Meer weergeven The influence of the current density is shown in Fig. 9. In the case of Armco iron, two out of three samples with a charging current density of 10 mA/cm2in the acidic solution … Meer weergeven The hydrogen charging in a pressurized hydrogen atmosphere did not lead to a significant hydrogen absorption either in Armco iron or … Meer weergeven For the hydrogen charging under a sour gas atmosphere, the mean values and standard deviations were determined from two values. In … Meer weergeven WebIt has long been understood that hydrogen has a negative effect on metals like iron and steel. Studying this phenomenon is not easy because of the fact that hydrogen is …
