Cross-section analysis of the morphology of electrodeposited copper obtained in the hydrogen co-deposition range

Abstract

Cross-section analysis of copper deposits electrodeposited in the hydrogen co-deposition range at a constant overpotential and in a pulsating overpotential (PO) regime was performed. It was shown that a complete structural analysis of these technologically very important electrodes is impossible without an analysis of their internal structure. An insight into the compactness (or porosity) of the deposits, as well as into the depth of the holes, can only be obtained by this type of analysis.

Urađena je analiza poprečnih preseka taloga bakra dobijenih u oblasti ko-depozicije vodonika na konstantnoj prenapetosti i režimom pulsirajuće prenapetosti. Pokazano je da kompletna strukturna analiza ovih tehnološki veoma važnih elektroda nije moguća bez analize njihove unutrašnje strukture. Uvid u kompaktnost (ili poroznost) taloga, kao i u dubinu rupa može da se dobije samo ovim tipom analize.
