| 英文摘要 | The mechanism of passivation breaking by anaerobic sulfate-reducing bacteria (SRB) on passivated film of copper alloy was investigated in this article. The results confirm that under biogenic sulfide conditions, the dense passivation film composed of copper-oxide with high-protective ability on the surface of copper substrate gradually evolves into loose and porous copper-sulfide film with less-protective ability. This Cu2S film is more easily penetrated by corrosive anions and further accelerates the pitting of the copper alloy substrate. The Point Defect Model (PDM) for copper alloys in SRB-containing environment was established to explain the pitting process of passivation films under S2- corrosion, which describes how sulfur ions occupy oxygen vacancies resulting in a shift from Cu-O to Cu-S in passivation film. Meanwhile, the PDM quantifies the pitting process of S2on passivated film by calculating the resistance, capacitance, semiconductor properties and diffusion coefficient within the passivated film: the adsorbed S2- prevent or retard the re-passivation of the copper alloys through hindering the attachment of O atoms. The relationship between passivation film structure, electrical properties, semiconductor properties and its stability to corrosion resistance was analyzed. |
