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(shi)指金屬表面(mian)與離子導電(dian)(dian)(dian)的介質(zhi)發(fa)生電(dian)(dian)(dian)化學(xue)反(fan)應(ying)而引(yin)起的破(po)壞，是(shi)至少包(bao)含一對電(dian)(dian)(dian)極(ji)反(fan)應(ying)的腐(fu)蝕(shi)。電(dian)(dian)(dian)化學(xue)腐(fu)蝕(shi)是(shi)最(zui)(zui)普遍、最(zui)(zui)常(chang)見的腐(fu)蝕(shi)，例如金屬在大(da)氣(qi)、海水、土壤和(he)各種電(dian)(dian)(dian)解質(zhi)溶液(ye)中的腐(fu)蝕(shi)都屬此類。 陽(yang)極(ji)和(he)陰極(ji)是(shi)電(dian)(dian)(dian)接通的，電(dian)(dian)(dian)子可(ke)以在其間流動(dong)，它們接觸的電(dian)(dian)(dian)解液(ye)也是(shi)...
