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 influence of humidity on the corrosion behavior of steel materials in neutral soil was studied by means of weak polarization curves and electrochemical impedance spectroscopy. The results showed that the corrosion rates and corrosion potentials of carbon steel in soils with various humidities all continued with the corrosion But tends to a stable value.The stable corrosion current density of carbon steel has the maximum change with the humidity.Carbon steel soil erosion process is closely related to soil moisture.
