|electrolytic corrosion/galvanic corrosion;[化學]電化學腐蝕,電解腐蝕
Electrochemical corrosion(電化學腐蝕)是指金屬與周圍環境中的電解質發生電化學反應而導緻的腐蝕現象。以下是詳細解釋:
定義與原理
電化學腐蝕的本質是金屬表面形成微電池,通過氧化還原反應導緻金屬溶解。例如,鐵在潮濕環境中會與水、氧氣等電解質接觸,形成陽極(金屬被氧化)和陰極(還原反應發生區域),産生電流并加速腐蝕。
與化學腐蝕的區别
電化學腐蝕需要電解質(如水、鹽溶液)和電流參與,而純化學腐蝕僅通過直接化學反應發生(如高溫氧化)。
常見例子
影響因素
控制方法
可通過塗層防護、陰極保護(如犧牲陽極)或添加緩蝕劑等手段減緩。
電化學腐蝕是金屬材料失效的主要形式之一,廣泛存在于工業與自然環境中,需結合材料科學和環境控制進行防護。
電化學腐蝕是指金屬在電化學環境下受到的腐蝕。以下是該詞的詳細解釋:
電化學腐蝕是一種金屬腐蝕的形式,它是由電化學反應而産生的。金屬在電解質溶液中被氧化或還原,導緻電極産生電勢差并引起腐蝕。電化學腐蝕是一種常見的金屬腐蝕形式,可導緻材料的疲勞、裂紋和失效。
電化學腐蝕是由電化學反應引起的金屬腐蝕。當金屬表面與電解質接觸時,它會被氧化或還原,導緻電極産生電勢差并引起腐蝕。這種腐蝕形式通常發生在金屬表面有缺陷(如裂紋、劃痕或孔洞)的區域,這些區域容易形成局部電池,引起腐蝕。
電化學腐蝕的近義詞包括腐蝕、電化學腐蝕、金屬腐蝕等。
電化學腐蝕的反義詞是抗腐蝕。抗腐蝕是指金屬或材料具有抵禦腐蝕的能力,通常是通過塗層、合金或其他材料來實現。
