free corrosion potential

基本解释

Galvanic corrosion results of steel couples with various free corrosion potential difference and surface area ratio of cathode to anode in seawater have been obtained.
获取了不同电位差的钢偶对在海水中以不同面积比偶合的腐蚀结果；
Experiments show that the corrosion of steels under disbonded holiday on free corrosion potential is heavier than that on cathodic polarization potential on shorter immersing time.
试验结果表明，在较短的浸泡时间里，在阴极极化电位下涂层缺陷下方金属基体的腐蚀程度低于在自然腐蚀电位下的腐蚀程度；
Experiments have shown that, on free corrosion potential, the corrosion of carbon steels with disbonding defect of coating is heavier than that of breaking defect of coating with times.
结果表明，随着浸泡时间的延长，在自然腐蚀电位下，存在剥离涂层缺陷时碳钢的腐蚀程度高于破损涂层缺陷时碳钢的腐蚀程度；
