Abstract EN
Nickel-layered silicates were electrochemically deposited from acidic bath solutions.
Citrate was used as a ligand to stabilize nickel (II) ions in the plating solution.
The silicate, montmorillonite, was exfoliated by stirring in aqueous solution over 24 hours.
The plating solutions were analyzed for zeta-potential, particle size, viscosity, and conductivity to investigate the effects of the composition at various pHs.
The solution particles at pH 2.5 (−22.2 mV) and pH 3.0 (−21.9 mV) were more stable than at pH 1.6 (−10.1 mV) as shown by zeta-potential analysis of the nickel-citrate-montmorillonite plating solution.
Ecorr for the films ranged from −0.32 to −0.39 V with varying pH from 1.6 to 3.0.
The films were immersed in 3.5% NaCl and the open circuit potential monitored for one month.
The coatings deposited at pH 3.0 were stable 13 days longer in the salt solution than the other coatings.
X-ray diffraction showed a change in the (111)/(200) ratio for the coatings at the various pHs.
The scanning electron microscopy and hardness results also support that the electrodeposition of nickel-montmorillonite at pH 3.0 (234 GPa) had improved hardness and morphology compared to pH 2.5 (174 GPa) and pH 1.6 (147 GPa).
