中文摘要:
      目的 揭示黑色金属腐蚀速度与土壤环境因子之间的关系。方法 分析Q235B碳素结构钢、X70 和X80 管线钢的腐蚀质量损失率和点蚀深度等数据, 与土壤的矿物组成和理化性质进行比较。 结果 三种钢在江西鹰潭土壤中的腐蚀最为严重, Q235B钢在其他七种土壤中腐蚀状况没有显著性差异, X70管线钢在黑龙江大庆和辽宁沈阳的腐蚀质量损失率较其他非酸性土壤高, 而X80管线钢腐蚀状况在各土壤中遵循江西鹰潭>黑龙江大庆>辽宁沈阳=山东大港≥四川成都=西藏拉萨≥新疆库尔勒≥青海格尔木的规律。结论 江西鹰潭红壤中三种钢腐蚀速率高的原因可能在于不均匀的土壤质地, 粘粒含量较高使得土壤适宜腐蚀的水分含量保持时间较长和土壤酸度较高。
英文摘要:
      Objective To elucidate the relationship between the corrosion rate of three ferrous metals and the associated soil properties. Methods The weight loss due to corrosion and the pitting depth of Q235B steel, X70 and X80 pipeline steels were analyzed and compared with the composition and the physicochemical properties of soil minerals. Results The worst corrosion of three studied ferrous metals was observed in the red soil in Yingtan, Jiangxi Province. The differences of corrosion rate in the other seven soils were not significant for Q235B steel. The significant larger weight losses of X70 pipeline steel in the non-acidic soils were found in the soils in Daqing and Liaoning, located in Heilongjiang and Liaoning Provinces, respectively. The corrosion rate of X80 pipeline steel in the studied soils followed the order: Yingtan, Jiangxi>Daqing, Heilongjiang>Shenyang, Liaoning=Dagang, Shandong≥Chengdu, Sichuan=Lhasa, Tibet≥Korla, Xinjiang≥Golmud, Qinghai. Conclusion The highest corrosion rate of three ferrous metals in the red soil was most likely resulted from the heterogeneous texture as the high content of clays caused long maintenance of moisture and high soil acidity.
