Effects of hydrogen and tensile stress on passivity of carbon steel
Abstract
The passivity degradation of carbon steel can be characterised by its low resistance to breakdown, high passive current density and retarded passivation. It can be caused by tensile stress well below the yield strength of steel. This effect is significantly enhanced when dissolved hydrogen is present in steel. The passivity degradation is found to be related to formation of a passive film containing more defects.
