The morphology of copper powder obtained by different regimes of electrolysis

Abstract

The effect different deposition regimes (constant and reversing currents), on the powdered copper electrodeposits morphology were investigated. The morphology of electrodeposited copper powder were investigated using a scanning electron microscope (SEM). The effect of the current amplitude cathodic to anodic time ratio and period of the current wave are discussed. It is shown that the parameters determining the reversing current wave determine the micromorfology of the copper powder particles deposited.

Ispitivan je uticaj različitih režima elektrolize (konstantna i reversna struja) na morfologiju bakarnog praha. Morfologija istaloženog bakarnog praha je proučavana pomoću skening elektronskog mikroskopa (SEM). Diskutovan je efekat katodne i anodne amplitudne gustine struje, odnos katodnog i anodnog vremena kao i vremena katodnog taloženja i anodnog rastvaranja. Pokazano je da parametri koji određuju oblik talasa reversne struje određuju i mikromorfologiju čestica istaloženog bakarnog praha.
