大气腐蚀（Atmospheric Corrosion）是指金属材料暴露于地球自然大气环境中，在环境因素（如水分、氧气、污染物）作用下发生的电化学腐蚀过程。它是全球范围内最普遍且造成经济损失最大的腐蚀类型之一。其核心机制可概括如下：
定义与核心机制
大气腐蚀本质上是薄液膜下的电化学过程。当金属表面吸附大气中的水分（如露水、雨水、高湿度形成的冷凝水）形成微观或可见的电解液薄膜时，金属发生阳极溶解（氧化反应），同时氧气在阴极区域发生还原反应，共同构成腐蚀电池。反应通式可表示为：
阳极反应： $ce{M -> M^{n+} + ne^{-}}$ （M代表金属）
阴极反应： $ce{O2 + 2H2O + 4e^{-} -> 4OH^{-}}$ （中性或碱性环境）
腐蚀产物（如铁锈 $ce{Fe2O3·nH2O}$）在此过程中形成并积累于金属表面。
关键影响因素
腐蚀产物与特征
腐蚀产物层（锈层）的结构和性质对后续腐蚀速率有重要影响。例如：
