摘要：

The surface film formed on strained mild steel in 0. 5N H//2SO//4 containing 0. 005N Kl was examined by XPS (X-ray Photoelectron Spectroscopy) in connection with the SCC (Stress Corrosion Cracking) susceptibility which is highest around 0. 06 V relative to the corrosion potential. The film was found to consist mainly of FeOOH containing small amounts of sulfur and iodide. The iodide content alone varied with the polarization potential and had a critical potential coinciding with that for the SCC susceptibility, which is explained by the instability of the surface film at the potential.
