英文摘要	Joint density functional theory calculations have been performed to investigate the interactions of atomic oxygen and chlorine with the Fe(110) and Cr-doped Fe(110) surfaces both in vacuum and in aqueous solution. The results show that Cr doping on the top of surface makes the atomic oxygen adsorption more thermodynamically favorable but slightly decreases the absorbability of chlorine. Subsurface doping atom makes little contribution to the adsorption characteristics of the cases considered in this study, which indicates that doping on the first layer is a reasonable and simplified approach for studying adsorption properties on iron surfaces. The adsorption strength of O decreases on Cl pre-adsorbed surfaces, demonstrating a competition relationship between the two species. This result is consistent with the adsorption theory of passivation, which attributes Clinduced corrosion to its inhibition of oxygen adsorption. Cr surface doping can significantly decreases the negative effects caused by chloride ion, resulting in the formation of protective oxide film.
