“…Dendriti olova pripadaju grupi 2-D dendrita sa granama koje leže u istoj ravni sa stablom. Primarni (P) dendriti su formirani iz osnovnih (nitratnih) [10] (slike 8a i b), dok razgranatiji sekundarni (S) dendriti su formirani elektrohemijskim taloženjem iz kompleksnih (acetatnog) elektrolita (slike 8c i d) [11]. Taloženje iz hidroksilnog elektrolita (slike 8e i f) može da dovede i do pojave tercijarnih grana, tako da se i dendriti (T) tipa mogu formirati u procesu taloženja olova iz kompleksnih elektrolita [17].…”

The polarization and morphological characteristics of powder forms of the group of the intermediate metals were examined by the analysis of silver and copper electrodeposition processes at high overpotentials. The pine-like dendrites constructed from the corncob-like forms, which are very similar to each other, were obtained by electrodeposition of these metals at the overpotential belonging to the plateaus of the limiting diffusion current density. A completely different situation was observed by the electrodeposition of silver and copper at the overpotential outside the plateaus of the limiting diffusion current density in the zone with the fast increase in current density with the overpotential. Silver dendrites, which were very similar to silver and copper dendrites obtained inside the plateaus of the limiting diffusion current density, were obtained at the overpotential outside the plateau. Due to the lower overpotential for hydrogen evolution for copper, hydrogen produced during the copper electrodeposition process strongly affected the surface morphology of copper. The same shape polarization curves with completely different surface morphologies of Cu and Ag electrodeposited at overpotentials after the inflection point clearly indicate the importance of morphological analysis in the investigation of polarization characteristics of the electrodeposition systems. The role of hydrogen as a crucial parameter in the continuous change of copper surface morphology from dendrites to honeycomb-like structures was investigated in detail. On the basis of this analysis, the transitional character of the intermediate metals between the normal and inert metals was considered. The typical powder forms characterising electrodeposition of the intermediate metals were also defined and systematized.Keywords: electrodeposition; copper; silver; dendrite; hydrogen; pores; cauliflower-like forms СПОРЕДБА НА ПОЛАРИЗАЦИОНИТЕ И МОРФОЛОШКИТЕ КАРАКТЕРИСТИКИ НА ЕЛЕКТРОХЕМИСКИ СОЗДАДЕНИ ПРАШКОВИДНИ ОБЛИЦИ НА ИНТЕРМЕДИЈАРНИ МЕТАЛИПреку анализа на процесите на електродепозиција на сребро и бакар при високи пренапони беа испитувани и споредувани поларизационите и морфолошките карактеристики на прашоци од интермедијарни метали. При електродепозиција на овие метали со пренапони што припаѓаат на платото на гранична дифузиона густина на струјата, беа добиени дендрити во вид на бор изградени од елементи слични на кочан од пченка, кои се многу слични еден на друг. Наполно поинаква состојба беше утврдена при електродепозиција на овие метали со пренапони надвор од платото на гранична дифузиона густина на струја во делот на брз пораст на густината на струјата. Дендрити на среброто, многу слични на оние на дендритите на сребро и бакар добиени при пренапони што припаѓаат на платото на гранична дифузиона густина на струјата, беа добиени при пренапони надвор од оние на платото. Поради помалиот пренапон за издвојување на водород врз бакар, водородот создаден врз овој метал нагласено ја менуваше морфологијата на површината на бакарот. Истиот облик на п...
