摘要：

The oxide film on 304 stainless steel exposed to the hydrothermal environments at 573.15 K up to 20 days without/with 10 ppb Zn injection has been investigated ex situ by X-ray photoelectron spectroscopy (XPS). ZnFe2O4 and ZnCr2O4 were found to be formed in the oxide film at the initial stage of immersion by substitution reaction between Zn2+ and Fe2+, and ZnCr2O4 became dominant after long-term immersion. The calculations of potential-pH diagrams, solubilities and crystallographic features of spinels have been done to evaluate the oxide film structure and the inhibition mechanism caused by Zn injection.
