【請教】開路電勢(OCP)是什么意思
|
||
|
本人剛剛接觸到金屬腐蝕與防護(hù)的研究,不懂的太多,想請教大家兩個問題: 1、測阻抗都是在開路電勢下測試嗎?開路電勢值的高低表示什么意思? 2、測定極化曲線時,最佳電勢范圍怎么確定?一定要是在腐蝕電勢之前嗎?如果測出來有些數(shù)據(jù)的I=0,塔菲爾曲線怎么做? 急盼大家的幫助,非常感謝! |

| The open circuit (oc) potential is the potential of the working electrode relative to the reference electrode when no potential or current is being applied to the cell. When a potential is applied relative to oc, the system measures the open circuit potential before turning on the cell, then applies the potential relative to that measurement. For example, if the initial potential is set to +100 mV vs. oc in the software and the measured open circuit potential is +300 mV, then the initial potential will be set to +400 mV. |
