Abstract Annealed pure specimens were pre-charged with hydrogen at virous current densities.Effect of hydrogen on anodic polarization and passivation process of nickel was investigated using electrochemical method and theoretical analysis.The results showed that precharged hydrogen shifted the self-corrosion potential negative,diminisked passived potential region,in Na2B4O7 solution.After charged with hydrogen and then passisived film in NaCl solution decreased with the increase in hydrogen content.
