To study the corrosion behavior of carbon steel in seawater at different temperatures, a novel electrochemical method called gradient-distributed wire beam electrode technique with high temporal and spatial resolution has been employed. This new wire beam electrode was prepared by three kinds of carbon steel with different carbon contents so that it can evaluate three materials simultaneously in the same corrosion medium (3.5wt.% NaCl solution) and improve the accuracy of tests results. After the gradient-distributed wire beam electrode soaked in 3.5wt.% NaCl solution for 8h, compared with measured at room temperature, the corrosion rate was accelerated greatly and polarity reversal of potential-current was also observed.

温度对浸入 3.5 wt.% NaCl 溶液中的低碳钢梯度分布 WBE 的影响

为了研究碳钢在不同温度下海水中的腐蚀行为，采用了一种新的电化学方法，称为梯度分布线束电极技术，具有高时空分辨率。这种新型线束电极由三种不同碳含量的碳钢制备而成，可以在相同的腐蚀介质（3.5wt.% NaCl溶液）并提高测试结果的准确性。梯度分布线束电极浸泡在 3.5wt.% NaCl 溶液 8h，与在室温下测量相比，腐蚀速率大大加快，并且还观察到电位-电流的极性反转。
