In this study, cobalt-nickel (Co-Ni) alloys were deposited electrochemically onto aluminum substrates under applied current densities of 103.8, 138.4, 173 and 207.6 A m −2 . Influence of the applied current density on the structural and magnetic properties of the Co-Ni alloys was investigated. The bath for Co-Ni alloys deposition was composed of 0.08 mol l −1 CoSO4·7H2O, 0.2 mol l −1 NiCl2·6H2O, 0.1 mol l −1 NiSO4·6H2O and 0.25 mol l −1 H3BO3. The electrochemical investigation of Co-Ni alloys was completed using cyclic voltammetry and galvanostatic studies. Inductively coupled plasma analysis has shown that the amount of the cobalt in the deposited alloy has decreased from 73.61% to 67.01% with the increase of the applied current density from 103.8 to 207.6 A m −2 . According to the magnetic analysis results, the values of coercivity coefficient of the deposited Co-Ni alloys range between 115 and 150 Oe, confirming ferromagnetic behavior of the alloys. Experiment results indicate that magnetic and structural properties of the Co-Ni alloy deposits are greatly influenced by the applied current density in the electrodeposition system.

“…According to the magnetic analysis results, the coercivity values of the Co-Ni films have ranged from 70 to 135 Oe, confirming ferromagnetic behavior of the alloys. Coercivity values of the magnetic materials mainly depend on the particle size and magneto crystalline anisotropy [29][30][31][32][33]. A decrease in grain size results in a decrease in the magnetic domain size, which results in lower coercivity values [34].…”

Cobalt-Nickel alloys have been widely used for decoration, in magnetic recording devices and corrosion resistance applications, etc. In this study, the influences of cobalt amount in electrolyte on the magnetic and structural properties of the electrodeposited Co-Ni alloys were investigated. An electrolyte solution, consisting of cobalt sulfate, nickel sulfate, nickel chloride and boric acid, was used in electrodeposition. The electrochemical investigation of Co-Ni alloys was completed using cyclic voltammetry and galvanostatic studies. The morphological and structural analyses of the alloys were performed using inductively coupled plasma, scanning electron microscopy, X-ray diffraction and vibrating sample magnetometer techniques. The effect of cobalt concentration on the magnetic properties, phase structure and grain size of the alloys was investigated. Magnetic hysteresis results indicate that the amount of the cobalt content in the electrolyte has a strong influence on the ferromagnetic behavior of fabricated alloys. Results of the study show that changing the electrodeposition parameters, such as composition of electrolyte solution, allows to fabricate alloys with different properties.

Copper zinc alloys were electrodeposited in the form of thin films. Electrodeposition process was carried out in non-cyanide aqueous medium, under constant current. Effect of pre-deposition ultrasonication of solution was investigated. In other words ultrasonic treatment was applied only before the electrodeposition. Solutions were subjected to high-energy ultrasonication for increasing times. Cyclic voltammetry was used to understand changes occurring due to duration of ultrasonication. No ultrasonication was applied during deposition. Atomic composition of resultant films were revealed by MP-AES. It was found that implementation of ultrasonic treatment before electrodeposition affects CV characteristics, when compared to non-ultrasonicated solution. Atomic composition of fabricated samples were found to be close to each other, some of them showing more deviation.
