free corrosion potential

基本解釋

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(duì)在海水中以不同面積比偶合的腐蝕結(jié)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.
試驗(yàn)結(jié)果表明，在較短的浸泡時(shí)間里，在陰極極化電位下涂層缺陷下方金屬基體的腐蝕程度低于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(jié)果表明，隨著浸泡時(shí)間的延長(zhǎng)，在自然腐蝕電位下，存在剝離涂層缺陷時(shí)碳鋼的腐蝕程度高于破損涂層缺陷時(shí)碳鋼的腐蝕程度；
