1Cr13不锈钢的土壤腐蚀行为

Corrosion Behavior of 1Cr13 Stainless Steel in Soils

通过在酸性、中性及碱性土壤中埋设试件的方法,研究了1Cr13不锈钢分别经过1年、3年、5年这三种试验周期后的腐蚀行为特征。结果表明,1Cr13不锈钢在酸性及中性土壤中腐蚀轻微;在高盐碱性土壤中腐蚀严重,而且以点蚀为主。土壤中Cl-及SO2-4是影响1Cr13不锈钢腐蚀行为的最主要因素,随着土壤中Cl-及SO2-4增多,1Cr13不锈钢的腐蚀失重近似线性增大。

The corrosion behavior of 1Cr13 stainless steel in soils were studied. The results show that the corrosion of stainless steel were mainly due to the total contents of Cl - and SO 2- 4 in soils, a good correlation between the weight loss of corrosion and the total contents of Cl - and SO 2- 4 in soils.
