| 摘 要： | 恒电流暂态法做为研究金属电沉积的有效工具广泛被采用。传统的恒电流暂态法需要用示波器及照相装置,操作较繁。本文利用Model-273恒电势仪和Apple-Ⅱ微机联用完成了恒电流暂态实验,利用该装置可使操作全部自动化,数据的采集、贮存、打印以及超电势与时间之间关系图的绘制全部由计算机完成,不仅操作简便,且精度高。在验证该装置可靠的基础上,本文用其测定了镁在二甲基甲酰胺中电沉积的动力学参数。不仅加深了对镁

| Abstract: | The electrodeposition of magnesium in dimethylformamide has been studied by means of galvanostatic method The overpotential has been recorded during constant current pulses with a duration time that permits only a few monolayers deposition per pulse The experiments were carried out under conditions aimed at reducing contamination of the electrode surface. The kinetics coefficients of electrodeposition of Mg have been measured. The electron transfer step in the electrodeposition of Mg is the ratedetermining step has been confirmed in this book. |
