摘要

讨论了以高交换电流密度为沉积特征的金属枝晶生长的机理。结果表明，在这种情况下，在极低过电位的恒电位沉积中，树突生长是可能的。在恒流沉积中，树枝状生长也是可能的。还表明，在低过电位下，瞬时树突生长是不可能的。以硝酸铅溶液中铅的电结晶实验研究为例进行了讨论。

Dendritic electrocrystallization of lead from lead nitrate solution

The mechanism of dendritic growth initiation for metals whose deposition is characterized by high exchange current densities is discussed. It is shown that in this case dendritic growth is possible at very low overpotentials in potentiostatic deposition. Dendritic growth is also possible in galvanostatic deposition. It is also shown that instantaneous dendritic growth is not possible at low overpotentials. The discussion is exemplified by an experimental study of the electrocrystallization of lead from lead nitrate solution.
