“…The current environmentally assisted cracking (EAC) models for hydrogen embrittlement [74], do not incorporate, nor account for, the local chemical/electrochemical effects arising from the presence/exit of absorbed H. H, besides activating the anodic dissolution (this work), and promoting pit initiation/propagation [26, 27, 28, 29, 30, 31, 32, 33, 34], could also reduce a number of species in the electrolyte [24, 25]; with all these factors causing changes in local chemistry, and consequently impacting EAC. The threshold H concentration below which there is no significant effect of H on steel dissolution, is an important parameter which will need to be determined in future work.…”
