"Accelerated corrosion"（加速腐蝕）是指通過人為控制實驗條件，在短時間内模拟材料在自然環境中長期暴露所産生的腐蝕現象。該技術廣泛應用于材料科學、工程防護和産品質量評估領域，其核心原理是通過提高腐蝕介質濃度、溫度、濕度或施加電化學激勵等方式加速腐蝕進程。
在工業實踐中，加速腐蝕測試需要遵循國際通用标準。美國材料與試驗協會（ASTM）發布的ASTM G85标準規定了改性鹽霧試驗方法，通過調節氯化鈉溶液濃度和pH值加速金屬腐蝕。中國國家标準GB/T 19292.4-2019則基于ISO 9223标準，建立了大氣腐蝕性的分類評估體系，為加速腐蝕試驗提供環境參數基準。
值得注意的是，美國腐蝕工程師協會（NACE）在《材料性能》期刊中指出，有效的加速腐蝕試驗必須滿足三個相關性原則：腐蝕機理、動力學過程和産物形态均需與自然腐蝕保持一緻。例如汽車行業進行的循環腐蝕試驗（CCT），通過交替模拟幹濕環境，能在200小時内重現車輛零部件2-5年的實際腐蝕效果。
“Accelerated corrosion”是材料科學和工程領域的專業術語，指通過人為控制環境條件（如溫度、濕度、化學介質濃度等），加速材料腐蝕過程的實驗方法或現象。以下是詳細解釋：
