鋼管電化學腐蝕（electrochemical cor-rosion）與防護設計
電(dian)(dian)(dian)(dian)化學腐蝕(shi)是(shi)(shi)指金(jin)屬(shu)(shu)表面與離子導電(dian)(dian)(dian)(dian)的(de)(de)介質發(fa)生電(dian)(dian)(dian)(dian)化學反(fan)應而引起(qi)的(de)(de)破壞，是(shi)(shi)至少包含一(yi)對(dui)電(dian)(dian)(dian)(dian)極反(fan)應的(de)(de)腐蝕(shi)。電(dian)(dian)(dian)(dian)化學腐蝕(shi)是(shi)(shi)最(zui)普遍、最(zui)常見的(de)(de)腐蝕(shi)，例(li)如金(jin)屬(shu)(shu)在(zai)大氣(qi)、海水、土壤和各種電(dian)(dian)(dian)(dian)解(jie)(jie)質溶液(ye)(ye)中的(de)(de)腐蝕(shi)都(dou)屬(shu)(shu)此類(lei)。 陽極和陰極是(shi)(shi)電(dian)(dian)(dian)(dian)接通的(de)(de)，電(dian)(dian)(dian)(dian)子可以(yi)在(zai)其(qi)間流動，它(ta)們接觸的(de)(de)電(dian)(dian)(dian)(dian)解(jie)(jie)液(ye)(ye)也是(shi)(shi)...
