    • Abstract
  • 316 L stainless steel welded joints was prepared by tungsten-arc inert gas (TIG) welding. The corrosion behavior of the TIG welded joints of 316 L stainless steel in different concentrations of H2S solutions are studied by polarization curves, electrochemical impedance spectroscopy (EIS), Mott-Schottky plots, and immersion corrosion experiments. Polarization curves and EIS results show that the corrosion current densities of the joints significantly increased as the concentration of H2S solutions increasing, while the corrosion potential decreased. Additionally, for the samples in the same concentration of H2S solutions, the 316 L base material shows the lowest corrosion current densities, next is the heat-effected zone, the welded zone presents the highest corrosion current densities. Mott-Schottky plots show that the passive films appear a p-n heterojunction, and the donor and acceptor densities reach 1 022 cm-3, showing a highly defective character of the passive film. The donor and acceptor densities increase with increasing H2S concentrations. The decreased passivity and the increased doping density affect the protectiveness of the passive film toward corrosion.
