鋼管電化學腐蝕(electrochemical cor-rosion)與防護設計
電(dian)(dian)化(hua)(hua)學(xue)(xue)腐(fu)(fu)蝕(shi)(shi)(shi)是(shi)指金(jin)屬(shu)(shu)表面(mian)與(yu)離子導(dao)電(dian)(dian)的(de)(de)(de)(de)介(jie)質(zhi)發生電(dian)(dian)化(hua)(hua)學(xue)(xue)反應(ying)而引起的(de)(de)(de)(de)破壞,是(shi)至少包含一對電(dian)(dian)極反應(ying)的(de)(de)(de)(de)腐(fu)(fu)蝕(shi)(shi)(shi)。電(dian)(dian)化(hua)(hua)學(xue)(xue)腐(fu)(fu)蝕(shi)(shi)(shi)是(shi)最(zui)普遍(bian)、最(zui)常見的(de)(de)(de)(de)腐(fu)(fu)蝕(shi)(shi)(shi),例如(ru)金(jin)屬(shu)(shu)在大氣、海(hai)水、土壤和各(ge)種電(dian)(dian)解質(zhi)溶液(ye)中的(de)(de)(de)(de)腐(fu)(fu)蝕(shi)(shi)(shi)都屬(shu)(shu)此類。 陽極和陰極是(shi)電(dian)(dian)接通的(de)(de)(de)(de),電(dian)(dian)子可以在其間流(liu)動,它們接觸的(de)(de)(de)(de)電(dian)(dian)解液(ye)也是(shi)...
