Formation of powdered copper deposits by constant and pulsating overpotential electrolysis
TLDR
In this paper, the possibility of electrodepositing copper powder by pulsating overpotential was shown, and it was shown that the grain size and the morphology of deposited powder is a function of overpotentials, and of amplitude and frequency of pulsation in constant and pulsatingoverpotential deposition respectively.Abstract:
The possibility of electrodepositing copper powder by pulsating overpotential is shown. These powders are compared to the powders obtained by constant overpotential electrodeposition. It is also shown that the grain size and the morphology of deposited powder is a function of overpotential, and of amplitude and frequency of pulsation in constant and pulsating overpotential deposition respectively.read more
