The authors investigated deopsits of Zn-Ni alloys from a ZnCl2-NiCl2-EMIC ambient-temperature molten salt bath with various organic solvents added. It was found that the organic solvents had an effect on the surface morphology of alloys and the deposition conditions. The electrodeposit, which had a smooth, glossy, and crack-free surface, was obtained at low current density using ethylene glycol as a solvent. In addition, a smoother, denser, and more uniform deposition was performed by agitation applying gas bubbling. A crack-free and smooth amorphous Zn-Ni deposit was obtained under the conditions of 80°C, 2.0mA ⋅ cm–2, and 1.0mol% NiCl2 content in a bath with gas bubbling.
