摘要：
The effect of sulfide (S2-) ions on the corrosion behavior of an austenitic steel (Uranus B6) in phosphoric acid (H3PO4) solutions was examined. The critical concentration at which the effect of S2- ions became perceptible was determined. Aggressive effects of the ions increased with increases in temperature and oxygen content. Results showed S2- ions modified the cathodic and anodic processes.
