在材料科學與工程領域，"degradation mechanism"（退化機制）指材料或系統性能隨時間逐漸劣化的物理、化學或電化學過程。該術語包含兩個核心要素：
退化本質
材料性能衰退的根源性規律，通常由微觀結構變化引發。金屬材料的晶間腐蝕和聚合物材料的光氧化裂解是典型示例。美國材料試驗協會（ASTM）将這類機制定義為"導緻材料關鍵特性不可逆損失的物質轉化過程"（ASTM E1823标準）。
作用機理
包含四個關鍵階段：
以锂離子電池為例，其容量衰減涉及正極材料層狀結構坍塌和電解質分解産生界面膜等多重耦合機制。美國能源部可再生能源實驗室（NREL）的研究表明，溫度梯度引發的非均勻锂沉積是電池老化的主導因素之一。
“Degradation mechanism”是由“degradation”（退化/降解）和“mechanism”（機制）組成的術語，指導緻物質、系統或狀态發生退化或降級的具體過程或作用方式。以下是詳細解釋：
如需進一步了解具體案例，可參考環境科學或材料工程領域的專業文獻。
