陰極極化（Cathodic Polarization）是電化學中的一個重要概念，指在外加電流作用下，陰極的電極電位偏離其自然平衡電位向更負方向移動的現象。這種現象通常發生在金屬腐蝕或電化學沉積過程中，通過抑制陰極還原反應（如氧還原或氫離子還原）來減緩金屬溶解速率，從而實現腐蝕防護。
其核心機制涉及以下兩點：
在工程實踐中，陰極極化被廣泛應用于海洋設施（如船舶、石油平台）的防腐保護，以及锂電池、燃料電池等新能源器件的性能優化。美國腐蝕工程師協會（NACE）标準指出，将鋼結構極化至-0.85 V（相對于銅/硫酸銅電極）可有效抑制鐵基材料的腐蝕反應。
該理論的基礎可追溯至1930年代Wagner和Traud提出的混合電位理論，相關數學模型可表示為： $$ E = E_{eq} - eta_c eta_c = frac{RT}{alpha nF} lnleft(frac{i}{i_0}right) $$ 其中$eta_c$為陰極過電位，$i$為電流密度，$i_0$為交換電流密度。
陰極極化（cathodic polarization）是電化學中的一個重要概念，指在外加電流作用下，陰極的電極電位偏離其自然平衡狀态的現象。這種現象通常表現為陰極電位向更負的方向移動，導緻電流密度降低，從而減緩金屬的腐蝕速率。
基本定義
陰極極化是電極極化的一種類型，特指陰極（還原反應發生的電極）在通電後電位的變化。當外部電流通過陰極時，電極表面電荷分布改變，導緻其實際電位偏離平衡電位（即極化）。
相關參數與特性
應用領域
陰極極化的程度受多種因素影響，包括電解質成分、溫度、電流密度等。例如，在含有緩蝕劑的溶液中，陰極極化可能增強，從而更有效地抑制金屬腐蝕。此外，極化現象的研究也為理解電極反應動力學提供了理論依據。
