几种腐蚀性因子对海底土腐蚀性影响的初步研究
A effect of corrosive factors on corrosiveness of sea bed sediment

摘要: 在室内可模拟海底土腐蚀环境的电解池中研究了温度和电阻率对钢材在海土中腐蚀电极过程的影响以及温度、电阻率和硫酸盐还原菌对钢材在海土中腐蚀的影响.结果表明,温度升高、电阻率降低都能使钢在海土中的阴、阳极过程变得易于进行;而温度升高、电阻率降低、硫酸盐还原菌含量增加,将不同程度地加快钢材在海土中的腐蚀.Abstract: A cell designed to produce an anaerobic experimental environment modelling sea bed sediments was used to study the effects of temperature and resistivity on the electrode process and the effects of temperature,resistivity and sulphate reducing bacteria on the corrosion of steel in sediments.The results show that the catholic and anodic process of steel in sediments will conduct more easy when the temperature raises or the resistivity relutes,and the corrosion of steel will quicken in varying degrees in sediments when the temperature raises or the resistivity reduces or the sulphate reducing bacteria content raises.
