鋼管電化學腐蝕（electrochemical cor-rosion）與防護設計
電(dian)(dian)(dian)化學(xue)腐(fu)蝕(shi)是指(zhi)金屬表(biao)面(mian)與(yu)離子(zi)導電(dian)(dian)(dian)的(de)介質發生電(dian)(dian)(dian)化學(xue)反應而引起(qi)的(de)破壞，是至少(shao)包含一對電(dian)(dian)(dian)極反應的(de)腐(fu)蝕(shi)。電(dian)(dian)(dian)化學(xue)腐(fu)蝕(shi)是最普遍、最常(chang)見的(de)腐(fu)蝕(shi)，例如金屬在大氣、海水、土壤和(he)各(ge)種電(dian)(dian)(dian)解(jie)質溶液(ye)中的(de)腐(fu)蝕(shi)都屬此類。 陽極和(he)陰(yin)極是電(dian)(dian)(dian)接通的(de)，電(dian)(dian)(dian)子(zi)可以(yi)在其(qi)間流動，它(ta)們接觸的(de)電(dian)(dian)(dian)解(jie)液(ye)也是...
