Abstract
This study investigated the effect of alternating current (AC) on the electrochemical and stress corrosion cracking (SCC) behavior and mechanism of TA2 in a simulated marine solution. The increase in the open circuit potential and charge transfer resistance indicated that the passivation film remained undamaged by varying AC densities, indicating a low risk of SCC. However, under the synergistic effect of AC and direct current (DC), the potential significantly shifted negatively, leading to hydrogen evolution reactions and the formation of a hydride layer. This hydride-induced hydrogen embrittlement posed a potential risk to the integrity of TA2.
