Characterization and Morphology of Copper Powder Particles as a Function of Different Electrolytic Regimes

摘要

The effect different deposition regimes (constant and reversing currents), on the powdered copperelectrodeposits morphology were investigated. The results obtained in constant regimes werecompared with those obtained in reversing regimes. The morphology of electrodeposited copperpowder were investigated using a scanning electron microscope (SEM). The effect of the currentamplitude, cathodic-to-anodic time ratio and period of the current wave are discussed. It is shown thatthe parameters determining the reversing current wave determine the micromorphology of the copperpowder particles deposited. On the other side, technological properties of powders depend on theirgranulometry and particle morphology. Very often one method is inadequate for characterization of themorphology of powder particles. This paper also studied different methods for clear describing of thecopper powder granulometry and morphology.
