corrosion fatigue test 中文意思是什麼
corrosion fatigue test
解釋
腐蝕疲勞試驗-
The formation of 3. 5 % nacl solution is almost similar to that of 3. 5 % nacl thin electrolyte layer, just the mass transfer rate of the oxygen in the layer is more quicker than in the solution ? the test shows that the crack growth rate of wet - corrosion fatigue of lc4cs aluminum alloy in the layer is quicker than in the solution, and also shows that morphology of fatigue fracture in the layer is evidently distinguished from in the solution
3 . 5 nacl溶液和3 . 5 nacl薄液層的化學組成幾乎完全相同，只是薄液層中氧的傳質速率較快。實驗結果顯示了在薄液層中， lc4cs鋁合金的濕腐蝕疲勞裂紋擴展速率，大於在3 . 5 nacl溶液中的速率。實驗還發現其疲勞斷口的形貌，也與3 . 5 nacl溶液中的有明顯區別。 -
Several key problems and their technical settlements were expounded emphatically, such as the accelerated corrosion test technique for aircraft structure under laboratory conditions, the evaluation technique for corrosion damage of anticorrosive coats, the distribution characteristics and their variation regularities of the corrosion damage and fatigue life, the corrosion equivalent relationship between the accelerated environment and the service environment, and the methods for theoretical analysis of the calendar life
重點對腐蝕環境下飛機結構加速腐蝕試驗技術、防腐塗層腐蝕損傷評定技術、腐蝕損傷和疲勞壽命的分佈特性及其變化規律、腐蝕當量關系和日歷壽命理論分析方法等幾個關鍵問題及其技術途徑進行了闡述和探討。
