We establish basic regularities of influence of sulfate-reducing bacteria on the biocorrosion of 17G1S-U steel. The mechanisms of degradation of steel surfaces are generalized by the methods of topographic analysis, microindentation, and fractographic diagnostics. We also propose inhibitors of biocorrosion and substantiate the efficiency of their application.

燃气总管钢表面的生物腐蚀和降解过程的局部化

建立了硫酸盐还原菌对17G1S-U钢生物腐蚀影响的基本规律。钢材表面的退化机制通过形貌分析、显微压痕和断口诊断的方法进行了概括。我们还提出了生物腐蚀抑制剂并证实了它们的应用效率。
