主　　题：Ti-6Al-4V alloy Hydrogen charging Electrochemical corrosion Passive film 

摘      要：This study employs advanced electrochemical and surface characterization techniques to investigate the impact of electrochemical hydrogen charging on the corrosion behavior and surface film of the Ti-6Al-4V *** findings revealed the formation ofγ-TiH andδ-TiH_(2) hydrides in the alloy after hydrogen *** hydrogen charging resulted in more significant degradation of the alloy microstructure,leading to deteriorated protectiveness of the surface *** trend was further confirmed by the electrochemical measurements,which showed that the corrosion resistance of the alloy progressively worsened as the hydrogen charging time was ***,this work provides valuable insights into the mechanisms underlying the corrosion of Ti-6Al-4V alloy under hydrogen charging conditions.
