Abstract

The effects of pre-charged hydrogen on electrochemical behavior of Alloy 690 in solutions of various bicarbonate concentrations were investigated by measurements of open circuit potential, anodic polarization curves and electrochemical impedance spectroscopy. Charged-hydrogen shifted the open circuit potential in the negative direction, decreased the electrochemical impedance, increased the anodic current density. In general, charged hydrogen accelerated the interfacial reaction kinetics for Alloy 690 in bicarbonate solutions.
