摘要

The effect of hydrogen on the corrosion behavior of FeCrV medium entropy alloy in a 0.5 M H₂SO₄ solution was studied by electrochemical methods. The composition change of the passive film was analyzed using X-ray photoelectron spectroscopy. The results shown that after hydrogen charging for 12 h, the anodic current density of FeCrV samples increased, while the polarization resistance exhibited an opposite trend from 1.4 × 10⁴ to 5.9 × 10³ Ω cm², indicating a weakening of corrosion resistance. Moreover, the ratio of O^2- to OH^- in passive film decreased from 0.92 to 0.53 after charging for 12 h.
