A novel hydrogen charging method for stress corrosion cracking
In this paper* the authors introduce a novel in-situ hydrogen charging method for stress corrosion cracking testing in a high-temperature and high-pressure water environment at 325oC for the first time.
This method effectively mitigates the interference of the electrochemical charging on the corrosion potential, and the limitation of maintaining a stable hydrogen concentration in the materials using any pre-charge methods.
Post-experimental characterisation reveals that DiffH has a significant impact on the oxidation behaviour near the crack tip, suggesting a complex role of DiffH on stress corrosion cracking.
