Electrodeposition of Co-Ni-MoxOy Powders: Part I. The Influence of Deposition Conditions on Powder Composition and Morphology

Abstract

The Co-Ni-Mo x O y powders were obtained electrochemically at a constant current density from ammonia electrolyte. Ni and Co were anomalously deposited, inducing Mo deposition, which cannot be deposited separately from aqueous solutions. The obtained Co-Ni-Mo x O y powders were investigated by energy dispersive spectroscopy (EDS), X-ray diffraction (XRD), and scanning electon microscope (SEM) methods. Based on the obtained experimental results, it was concluded that the particle size of deposited powders is influenced by the chemical composition of the electrolyte and current density imposed. XRD results suggested that obtained powders were of amorphous structure, although a Co 3 Mo compound can be formed if certain experimental conditions are applied.

Synthesis of Sn-3.5Ag Alloy Nanosolder by Chemical Reduction Method

“…However, no obvious melting point depression behavior was observed, which might be due to the surface oxidation or heavy agglomeration of their synthesized nanoparticles. The solder alloy powders have been synthesized by various methods such as solid state melting process [12], electrolytic deposition [13] and chemical reduction [14]. The solid state melting process is a commonly used technique but the limitation is the minimum powder size.…”
