In this paper, the effect of sp. on the corrosion process of X65 steel was investigated by using non-targeted metabolomics techniques for comprehensive characterization of metabolites, combined with surface analysis techniques and electrochemical testing. The results showed that the organic acids produced by sp. accelerated the corrosion process of X65 steel in the early stage, and the presence of sp. promoted the deposition of stable corrosion products and minerals in the middle and late stages. In addition, proteoglycans and corrosion inhibiting substances were enriched on the metal surface, which enhanced the stability of the film. The combined effect of multiple factors makes the mixed film of biofilm and corrosion products more dense and complete, which effectively inhibits the corrosion of X65 steel.
本文采用非靶向代谢组学技术对代谢产物进行全面表征，并结合表面分析技术和电化学测试，研究了[具体菌种]对X65钢腐蚀过程的影响。结果表明，[具体菌种]产生的有机酸在早期加速了X65钢的腐蚀过程，而[具体菌种]的存在促进了中后期稳定腐蚀产物和矿物质的沉积。此外，蛋白聚糖和缓蚀物质在金属表面富集，增强了膜的稳定性。多种因素的综合作用使生物膜和腐蚀产物的混合膜更加致密和完整，有效抑制了X65钢的腐蚀。
