鋼管電化學腐蝕（electrochemical cor-rosion）與防護設計
電(dian)(dian)(dian)(dian)化學腐(fu)蝕是指金屬表(biao)面與離子(zi)導電(dian)(dian)(dian)(dian)的(de)(de)介質發(fa)生電(dian)(dian)(dian)(dian)化學反應而(er)引起的(de)(de)破壞，是至少包含一對電(dian)(dian)(dian)(dian)極反應的(de)(de)腐(fu)蝕。電(dian)(dian)(dian)(dian)化學腐(fu)蝕是最普遍、最常見的(de)(de)腐(fu)蝕，例如金屬在(zai)大氣、海水、土壤和(he)各種電(dian)(dian)(dian)(dian)解質溶液中的(de)(de)腐(fu)蝕都屬此類。 陽極和(he)陰極是電(dian)(dian)(dian)(dian)接通的(de)(de)，電(dian)(dian)(dian)(dian)子(zi)可以在(zai)其(qi)間流動，它(ta)們接觸的(de)(de)電(dian)(dian)(dian)(dian)解液也(ye)是...
