Abstract
In metal electrodeposition in the limiting diffusion current density range the deposition current density remains constant regardless of the deposition overpotential used. At the same time, the larger the deposition overpotential is the more disperse is the formed deposit, which is characterised by an increased specific surface. The difference in the specific surface of disperse deposits obtained at two different overpotentials in the limiting diffusion current density range is correlated with the difference between the deposition overpotentials. A method for the estimation of the surface tension of solid copper in copper sulfate solutions is also proposed.
Granična difuziona struja kod elektrohemijskog taloženja metala ne zavisi od primenjene prenapetosti u oblasti pune difuzione kontrole procesa. U isto vreme povećanje prenapetosti taloženja dovodi do nastajanja taloga veće specifične površine. Razlika specifične površine taloga dobijene na dve prenapetosti u oblasti pune difuzione kontrole procesa je povezana sa odgovarajućom razlikom prenapetosti i predložen je metod ocene površinskog napona čvrstog bakra u rastvorima bakar-sulfata.
