摘要
利用塔菲尔极化曲线技术、电化学阻抗技术和扫描电镜等方法研究了X70钢在不同湿度的卵石黄泥土中的腐蚀行为.结果表明,湿度对X70钢腐蚀的影响显著.随土壤湿度的增加,X70钢的腐蚀速率也增加.当含水量增大到25%时,腐蚀速率达到最大,然后腐蚀速率随着湿度增加而减小.
The corrosion behavior of X70 steel in yellow pebble soil with different moisture contents is studied by means of Tafel polarization, Electrochemical Impedance Spectroscopy and Scanning Electron Microscopy. It is found that moisture content has great influence on the corrosion behavior of X70 steel. The corrosion rate increases with the increase of soil humidity. It reaches a maximum when the moisture content is 25% and then decreases with the increase of soil humidity.
