periodic reverse plating

The influence factors on high-purity gallium electrolysis refining such as current density,NaOH concentration,platinum electrode,cyclical reverse electrolysis and so on were studied.

在高纯镓电解提纯的工业实践中,研究了电流密度、NaOH浓度、电极形式和周期反向电解等因素对电解过程的影响,确定了适宜的工艺生产控制条件。

It is the anode's passivation that hinders copper electrolysis current density, and using the current of period change direction can efficiently prevent the anode passivation,the current density can reach 400 A/ m2.

提高铜电解电流密度的主要障碍是阳极的钝化 ,用周期反向电流能相对地防止阳极钝化 ,从而电流密度可提高到 40 0A/m2 。

Two different periodical reversal currents, which are firstly used in electroforming research, are pulse reverse current and periodical reversal current without off-times in the negative current, respectively.

针对基于无背板生长工艺的微电铸模具高度不均匀问题,本文首次采用两种不同的周期换向电流进行了实验研究。

In this situation, the rotary electroplating was preferable.

在零件很大、电机功率不足或有特殊要求等情况下,常规电镀常无法满足工件加工要求,此时可采用旋转电镀方式来实现。
