Chronoamperometry was used to investigate phase transformations at the early stage of electrodeposition under potentiostatic stimuli. Whilst electrodeposition mostly occurs under galvanostatic stimuli, this work provides a new description using chronopotentiometry to analyse phase transformations during electrodeposition. With theoretical Ohm's law electro-relationship formula derivation, a non-dimensional plot between (Δ Δ ) and / was established similar to ( / ) / in the SH model. The non-dimensional plots were verified by the chronopotentiometry curve during gold electrodeposition. This work provides a new method of investigating phase transformation using chronopotentiometry during electrodeposition.
计时电流法用于研究恒电位刺激下电沉积早期的相变。虽然电沉积大多在恒电流刺激下发生,但这项工作提供了一种使用计时电位法分析电沉积过程中相变的新描述。通过理论欧姆定律电关系公式推导,建立了(Δ Δ )与 / 之间的无量纲图,类似于SH模型中的( / ) / 。通过金电沉积过程中的计时电位曲线验证了这些无量纲图。这项工作提供了一种在电沉积过程中使用计时电位法研究相变的新方法。
