| 摘 要： | 在含4种Cl-离子浓度的弱碱性中壤褐土中埋20#钢试样,经过2个月试验后,失重法测试样平均蚀速率和局部腐蚀扩展速率,结果表明,随着土壤中Cl-离子浓度提高,腐蚀腐蚀速率增加,并且Cl-离子浓度对局部腐蚀扩展速率的促进作用明显高于平均腐蚀速率。其中的两种Cl-离子浓度的埋样试样再经过4个月、6个月和8个月试验,仍显示上述规律。另外,文章结合中性和碱性土壤的腐蚀过程,讨论了Cl-离子浓度对中性和碱性土壤腐蚀速率影响的一般趋势。 |

| Abstract: | The 20#steel samples,which were buried in four different Cl-concentrations alkaline soil for two months,were test by the weight method to get the unifom and the local corrosion rate.The result showed that the rate increases with the increasing Cl-concentration and Cl-concentration had more influence on the local corrosion rate than the uniform corrosion rate.The samples of the two among the four different Cl-concentrations duried for four,six,eight months again,also showed the same result.Additionally,the p... |
