摘要
应用弱极化曲线技术和电化学阻抗谱研究了湿度对中性土壤中钢铁材料腐蚀行为的影响 .结果表明 ,各种湿度的土壤中碳钢的腐蚀速度和腐蚀电位均随着腐蚀的持续进行而趋于一个稳定值 ;碳钢的稳定腐蚀电流密度随湿度变化存在最大值 .碳钢土壤腐蚀过程与土壤湿度密切相关 .
The influences of moisture content on corrosion behavior of carbon steel in neutral soil were studied by low\|polarization curve technique. It was found that both the corrosion current density and corrosion potential reached a constant value with the development of corrosion of carbon steel in soils with different moisture content. The invariable soil corrosion current density of carbon steel had a maximum value with the variation of moisture content. At the same time, the controlling characteristic of soil corrosion is discussed.
