研究了酸性大气环境下建筑用L80钢腐蚀行为。结果表明,L80钢在气体温度60℃下腐蚀速率最低;整体上腐蚀速率随着腐蚀时间的增加呈下降趋势;含有H2S气体的环境能够阻碍腐蚀作用,使腐蚀速率下降;含有Cl-溶液和增加溶液流速均使腐蚀速率增加。
The corrosion behavior of L80 steel for construction in acid atmosphere was studied. The results show that L80 steel has the lowest corrosion rate at gas temperature of 60 ℃; the overall corrosion rate decreases with the increase of corrosion time; the environment containing H 2 S gas can hinder the corrosion and decrease the corrosion rate; the content of Cl- The solution flow rate increases the corrosion rate.
