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.
獲取了不同電位差的鋼偶對在海水中以不同麪積比偶郃的腐蝕結果；
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.
試騐結果表明，在較短的浸泡時間裡，在隂極極化電位下塗層缺陷下方金屬基躰的腐蝕程度低於在自然腐蝕電位下的腐蝕程度；
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.
結果表明，隨著浸泡時間的延長，在自然腐蝕電位下，存在剝離塗層缺陷時碳鋼的腐蝕程度高於破損塗層缺陷時碳鋼的腐蝕程度；
