Abstract

High manganese steel is a new generation of material for the fabrication of liquefied natural gas (LNG) storage tanks. The corrosion behavior of high manganese steel induced by iron-oxidizing bacteria (IOB) living in wastewater from LNG tanks bottom was investigated. The results revealed that IOB can induce a generation of a dense and thick biotransformation film on the steel. Interestingly, the biotransformation film could be able to reduce the corrosion rate of high manganese steel by 71 % and alleviate the formation of corrosion pits. A corrosion inhibition mechanism is postulated, elucidating the protective role of the iron-manganese oxide composite biofilm.

液化天然气储罐底部废水中的铁氧化细菌对高锰钢的腐蚀行为

高锰钢是制造液化天然气（LNG）储罐的新一代材料。研究人员对生活在液化天然气储罐底部废水中的铁氧化细菌（IOB）诱导的高锰钢腐蚀行为进行了调查。结果表明，IOB 能在钢材上诱导生成一层致密而厚的生物转化膜。有趣的是，生物转化膜能够将高锰钢的腐蚀速率降低 71%，并缓解腐蚀坑的形成。该研究推测了一种腐蚀抑制机制，阐明了铁锰氧化物复合生物膜的保护作用。
