摘要: 采用极化曲线、交流阻抗等技术对含水率在13% ~40%的X70钢腐蚀行为进行研究。结果表明,随
着土壤中含水率的增加,X70钢在鹰潭酸性土中腐蚀速率增加,含水率达到饱和时腐蚀速率达到最大;腐蚀形态由局
部腐蚀发展到全面腐蚀;含水率为13%时,阴极反应为吸氧反应,随着含水率的增加,H+ 和氧共同参与阴极反应。
土壤中的含水率与pH 值共同作用影响X70钢电化学行为。X70钢在鹰潭酸性土壤中的耐蚀性较差。

Abstract: The corrosion behavior of X70 steel in Yingtan acidic soil was studied by using polarization curve technique and electrochemical impedance spectroscopy (EIS) in 13%~40% water content. It is found that X70 steel corrosion rate is rised with the increasing of water content and reached a maximum value when the water content of soil is saturated, and samples is corroded selectively expanding roundly. Cathode reaction is oxygen reduction when water content is 13%, hydrogen ion then participated in with the water content increasing. Water content and pH both affect X70 steel electrochemical behaviors. Corrosion resisting property of X70 steel is bad in Yingtan acidic soil.
