阴极极化（Cathodic Polarization）是电化学中的一个重要概念，指在外加电流作用下，阴极的电极电位偏离其自然平衡电位向更负方向移动的现象。这种现象通常发生在金属腐蚀或电化学沉积过程中，通过抑制阴极还原反应（如氧还原或氢离子还原）来减缓金属溶解速率，从而实现腐蚀防护。
其核心机制涉及以下两点：
在工程实践中，阴极极化被广泛应用于海洋设施（如船舶、石油平台）的防腐保护，以及锂电池、燃料电池等新能源器件的性能优化。美国腐蚀工程师协会（NACE）标准指出，将钢结构极化至-0.85 V（相对于铜/硫酸铜电极）可有效抑制铁基材料的腐蚀反应。
该理论的基础可追溯至1930年代Wagner和Traud提出的混合电位理论，相关数学模型可表示为： $$ E = E_{eq} - eta_c eta_c = frac{RT}{alpha nF} lnleft(frac{i}{i_0}right) $$ 其中$eta_c$为阴极过电位，$i$为电流密度，$i_0$为交换电流密度。
阴极极化（cathodic polarization）是电化学中的一个重要概念，指在外加电流作用下，阴极的电极电位偏离其自然平衡状态的现象。这种现象通常表现为阴极电位向更负的方向移动，导致电流密度降低，从而减缓金属的腐蚀速率。
基本定义
阴极极化是电极极化的一种类型，特指阴极（还原反应发生的电极）在通电后电位的变化。当外部电流通过阴极时，电极表面电荷分布改变，导致其实际电位偏离平衡电位（即极化）。
相关参数与特性
应用领域
阴极极化的程度受多种因素影响，包括电解质成分、温度、电流密度等。例如，在含有缓蚀剂的溶液中，阴极极化可能增强，从而更有效地抑制金属腐蚀。此外，极化现象的研究也为理解电极反应动力学提供了理论依据。
