| 中文摘要: |
| 采用失重法、电阻法和方阻法测试碳钢在混凝土模拟溶液中的腐蚀深度,并利用极化曲线、交流阻抗测试探讨腐蚀电化学特征。在腐蚀深度为0.08 mm范围内,电阻法、方阻法与失重法测量的腐蚀深度最大差值分别为6.30μm和0.98μm,测量结果有较好的一致性。碳钢在浸泡开始时,表面有一层钝化膜,阻抗谱为单容抗弧;继续腐蚀,碳钢从钝化转变为活化,表面钝化膜遭到破坏,腐蚀溶解不断进行。 |
| 英文摘要: |
| The corrosion depth of carbon steel in simulated concrete solution was analyzed by mass loss, resistance and sheet resistance measurement, and electrochemical characteristics were discussed via potentiodynamic polarization, electrochemical impedance spectroscopy. Within the range of 0.08 mm, the maximum differences of corrosion depth of resistance and sheet resistance measurement were respectively 6.3μm and 0.98μm compared with the result of mass loss. The measurement of resistance and sheet resistance methods were consistent with that of mass loss. Initially passive characteristic was observed in the polarization curve and the electrochemical impedance spectroscopy was a single capacitive reactance arc, which indicated a layer of passive film on the surface of carbon steel. With the extension of time, passive state changed into active corrosion. Passive film on the surface of carbon steel broke down and corrosion proceeded. |
