electrochemical passivation 中文意思是什麼
-
The results show that in our research ptt ( pressure, time and temperature ) region the corrosion resistant effect of treated uranium depends on the treated time. the passivation film thickness maybe have an effect on the corrosion resistance. the electrochemical corrosion resistance of treated uranium in the solution ( 50ug / gcr ) has been studied by electrochemical measurement
在一定的溫度、壓力、時間范圍內，經超臨界co _ 2短時間處理的樣品其抗腐蝕性能有一定的提高，但效果不很明顯；經超臨界co _ 2和氣態co _ 2長時間處理的樣品其抗腐蝕性能顯著提高。 -
In this paper, rebar corrosion state was judged with three electrochemical nondestructive measuring technologies, i. e. half - cell potential, a. c. impedance and time potential. when the rebar was transformed from passivation to depassivation, it can obtain the chloride ions corrosion critical content through taking and analyzing chloride ions content around the rebar
本文利用半電池電位法、交流阻抗法和時間電位法三種電化學無損檢測技術判斷評估試件在試驗過程中鋼筋腐蝕狀況，當鋼筋由鈍化狀態轉為活化狀態時，取樣分析鋼筋周圍氯離子含量，得到了不同技術條件混凝土的氯離子臨界濃度。
