摘要：
The evolution of the passive films formed on duplex stainless steel 2205 in a chloride Solution was studied by X-ray photoelectron spectroscopy, and their compositions were analysed as a function of depth. The passive films oil the duplex stainless steel contained the oxides of the two main elements, i.e., Fe and Cr. The alloying elements were found to improve the corrosion resistance of duplex stainless steels; however, their content within the passive layer was negligible. A strong chromium enrichment was observed in the passive layers with increasing chloride concentration. The potentiodynamic measurements were used to determine the corrosion behaviour of duplex stainless steel under different concentrations of chloride solution.
