在材料科学与工程领域，"degradation mechanism"（退化机制）指材料或系统性能随时间逐渐劣化的物理、化学或电化学过程。该术语包含两个核心要素：
退化本质
材料性能衰退的根源性规律，通常由微观结构变化引发。金属材料的晶间腐蚀和聚合物材料的光氧化裂解是典型示例。美国材料试验协会（ASTM）将这类机制定义为"导致材料关键特性不可逆损失的物质转化过程"（ASTM E1823标准）。
作用机理
包含四个关键阶段：
以锂离子电池为例，其容量衰减涉及正极材料层状结构坍塌和电解质分解产生界面膜等多重耦合机制。美国能源部可再生能源实验室（NREL）的研究表明，温度梯度引发的非均匀锂沉积是电池老化的主导因素之一。
“Degradation mechanism”是由“degradation”（退化/降解）和“mechanism”（机制）组成的术语，指导致物质、系统或状态发生退化或降级的具体过程或作用方式。以下是详细解释：
如需进一步了解具体案例，可参考环境科学或材料工程领域的专业文献。
