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

This study investigates the effects of different deposition regimes, specifically constant and reversing currents, on the morphology of powdered copper electrodeposits. Using scanning electron microscopy (SEM), we compared the morphological characteristics obtained from both constant and reversing current regimes. The analysis revealed that parameters such as current amplitude, cathodic-to-anodic time ratio, and the period of the current wave play crucial roles in determining the micromorphology of the resulting copper powder particles. Furthermore, it was observed that the technological properties of the powders are influenced by their granulometry and morphological characteristics, emphasizing that a single characterization method is often insufficient for an accurate assessment of powder morphology. This paper also discusses various methods for effectively describing the granulometry and morphology of copper powders, which are essential for optimizing their applications in powder metallurgy. The findings contribute valuable insights into the relationship between electrodeposition processes and the resulting characteristics of copper powders, ultimately aiding in the development of more efficient production techniques.
