Abstract

Hydrogen permeation usually facilitates the corrosion of stainless steel remarkably. Herein, the corrosion behavior of a nickel-free high-nitrogen stainless steel (HNSS) containing 0.96 wt.% nitrogen with hydrogen charging is investigated by means of electrochemical measurements and x-ray photoelectron spectroscopy surface analysis. The results show that hydrogen charging not only increased the passive current density but also increased the pitting potential of HNSS. The increase in passive current density was attributed to the increased carrier density, depleted Cr content, and decreased O²⁻/OH⁻ ratio in the passive film, while the increase in the pitting potential resulted from the enrichment of N element in the passive film and the replacement of Ni with Mn in HNSS.
