考察金属电解沉积所需电能的各个组成部分。评论了节省能量的各种措施,其中包括使用具有低的氧超电压和尺寸稳定阳极(DSA)。将其作为电极反应电化学参数、电解质离子电阻率和电极内电子电阻率的函数,来计算平行电极上的电流密度分布。在铜电解沉积系统中,采用(DSA)阳极,从实验上证明了数学模型的正确性。使用尺寸稳定阳极所取得的能量节省,表明它主要受阳极基底内阻的影响。而动力学参数变化的影响则是次要的。
Investigate the various components of electrical energy required for electrolytic deposition of metals. Comments on various energy saving measures include the use of low oxygen overvoltage and dimensionally stable anodes (DSAs). The current density distribution on the parallel electrodes was calculated as a function of electrochemical reaction parameters of the electrode, the ionic resistance of the electrolyte, and the electronic resistivity within the electrode. In the copper electrodeposition system, the use of (DSA) anode, the experiment proves the correctness of the mathematical model. The energy savings achieved with a dimensionally stable anode indicate that it is primarily affected by the internal resistance of the anode substrate. The effect of dynamic parameter changes is secondary.
