The development of pitting corrosion on L245 carbon steel in a culture medium solution containing sulfate-reducing bacteria (SRB) was investigated. The results showed that the occurrence of corrosion in L245 carbon steel is closely linked to the evolution of biofilm and product film. As the test duration extended, overall corrosion was inhibited. Simultaneously, bacteria beneath the film layer promoted the generation and development of pitting corrosion, and the aggregation of bacteria (colonies) led to the aggregation of pitting corrosion.
研究了L245碳钢在含有硫酸盐还原菌(SRB)的培养基溶液中的点蚀发展情况。结果表明,L245碳钢的腐蚀发生与生物膜和产物膜的演变密切相关。随着试验时间的延长,整体腐蚀受到抑制。同时,膜层下方的细菌促进了点蚀的产生和发展,细菌(菌落)的聚集导致了点蚀的聚集。
