X70钢在氯化钠污染土中的模拟试验研究
Experimental on Corrosion of X70 Steel in Soil Polluted by NaCl
摘 要
通过室内模拟试验, 分析了密度、含水量、饱和度、含盐量、电阻率、氧化还原电位及腐蚀电位等污染土参数对X70钢的腐蚀行为影响, 并通过灰关联分析将这七种因素对X70钢腐蚀速率的影响进行了分析。结果表明,环境因素对X70钢在氯化钠污染土中腐蚀速率影响大小的顺序为氧化还原电位、含盐量、电阻率、腐蚀电位、含水量、密度、饱和度; 且氯化钠污染土中X70钢的腐蚀速率随着氧化还原电位的减小、含盐量的增大以及电阻率的减小而增大, 其中氧化还原电位对腐蚀速率的影响最大; 最后由Y-2000型X射线衍射仪分析可知, 腐蚀产物中主要为FeOOH、Fe3O4和Fe2O3。

Abstract
Density, water content, saturation, salt content, resistivity, redox potential and corrosion potential and other Parameters on the influence of corrosive behavior of X70 steel in Soil polluted by NaCl was tested in laboratory. The influence of these factors on the corrosive rate of X70 steel was analyzed through grey relative analysis comparatively. It substantiated that the order of the effects of environmental factors on corrosive rate of X70 steel in soil polluted by sodium chloride is: redox potential, salt content, resistivity, corrosion potential, water content, density, saturation; the corrosive rate of steel in Soil polluted by sodium chloride increases with the decrease of redox potential, the increase of the salinity and the decrease of resistivity, the redox potential's influence is most. Finally, by type Y-2000 X-ray diffraction analysis, corrosive products contain FeOOH, Fe3O4 and Fe2O3 mainly.
