Oral microbiota accelerates corrosion of 316L stainless steel for orthodontic applications
文献摘要：
In this work,microbiologically influenced corrosion(MIC)of 316L stainless steel(SS)caused by oral mi-crobiota was investigated with HOMINGS 16S rRNA gene sequencing technology,and electrochemical and surface analysis techniques.The results showed that oral microbiota from different subjects developed multi-species biofilms with significant differences in structure and composition of bacteria strains on the 316L SS coupons.In the presence of oral microbiota,more severe pitting corrosion and faster dissolu-tion of metallic ions including Ni and Cr were observed.The biofilm considerably decreased the pitting potential of 316L SS from 1268.0±29.1 mV vs.SCE(abiotic control)to less than 500 mV vs.SCE.The corrosion current density in the presence of oral microbiota from subject 1(115.3±83.3 nA cm-2)and subject 2(184.4±162.0 nA cm-2)was at least 4 times more than that in the abiotic medium(28.0±2.3 nA cm-2).The electroactive microorganisms with the potential to facilitate corrosion via extracellular electron transfer found in oral microbiota may be mainly responsible for the accelerated corrosion.
