生物污损对碳钢海水腐蚀的影响
Influence of Oceanic Biofouling on Corrosion of Carbon Steel in Seawater
摘 要
采用现场挂样,观测了在青岛、厦门海水中暴露0.25~4年的碳钢表面的污损生物和沉积锈层的外观、特性及其与腐蚀形貌的对应关系,用MPN法(最大可能数法)检测了污损生物和沉积锈层下的内锈层中的硫酸盐还原菌(SRB),讨论了生物污损与碳钢局部腐蚀的关系.结果显示,硬壳生物和锈层下的内锈层中均有SRB存在,大型生物污损、锈层外观和碳钢的腐蚀形貌有较好的对应关系:大型硬壳生物下腐蚀轻微,表面较平整,因为SRB活性和氧含量均很低,腐蚀速率低；而疏松的橘红色锈层覆盖下的钢/锈面,SRB活性高且有一定的氧含量,腐蚀速率较高.

Abstract
With the field exposure method,the appearance and characteristics of carbon steel exposed to the seawater in Qingdao and Xiamen for 0.25-4 years were observed,and their relationship was discussed.The SRB numbers in the internal rust layer of marine foulings and deposit rust layer were obtained with the Most Probable Number(MPN) method and then the relationship between biofouling and localized corrosion of carbon steel was disscussed.The results revealed that SRB existed in internal layer under both the marine foulings and deposit rust layer.The macrofouling and surface of rust layer corresponded well with the corrosion morphology of carbon steel.Corrosion on the surface covered with marine foulings with large hard shells was slighter than that covered with loose salmon pink rust layer because of lower activity of SRB and oxygen content.
