建筑用碳钢在盐水中的腐蚀行为研究

Corrosion Behavior of Carbon Steel Used in Construction in Salt Water

研究了建筑用碳钢在NaCl溶液和盐湖水中的腐蚀行为。结果表明,0～40 d期间盐湖水中碳钢进行＂选择性腐蚀＂,腐蚀速率较大;50～70 d期间碳钢发生类抛光作用;70 d时碳钢发生孔蚀等局部腐蚀现象。

Abstract： The corrosion behavior of the carbon steel used in construction in NaCl solution and salt-lake water was investigated. The results show that the so-called selective corrosion appears in the steel corroded during 0-40 d in the salt-lake water and the corrosion rate is a little faster. The polishing effect occurs during the corrosion of 50-70 d and the local corrosion such as pitting arises in the steel corroded for 70 d.
