主　　题：Stainless Steel Archaea Microbiological influenced corrosion 

摘      要：The corrosion behavior of 304 stainless steel(SS)in the presence of aerobic halophilic archaea Natronorubrum tibetense was *** 14 days of immersion,no obvious pitting pit was observed on the SS surface in the sterile *** contrast,the SS exhibited serious pitting corrosion with the largest pit depth of 5.0μm in the inoculated medium after 14 *** results of electrochemical tests showed that the barrier property of the passive film decreased faster in the inoculated *** X-ray photoelectron spectroscopy results indicated that the detrimental Fe2+and Cr6+increased in the passive film under the influence of archaea ***,which resulted in the accelerated deterioration of passive film and promoted the pitting *** with the energy starvation tests,the microbiologically influenced corrosion mechanism of 304 SS caused by halophilic archaea *** was discussed finally.
