Electrochemical Deposition of Zn-SiC Nanocomposite Coating and Investigation of its Corrosion Behavior in Marine Environments

Zn-SiC nanocomposite coatings were prepared from a sulfate bath solution by direct current electrochemical deposition. In this method, applied current density and concentration of nanoparticles in the bath were investigated as key parameters. Morphological and corrosion properties of these coatings were investigated by FESEM and potentiodynamic polarization in 1M NaCl solution respectively. In case of current density, an optimum percent of codeposited SiC nanoparticles was obtained at 0.1 A/cm2 by 0.96 vol.%. This was the highest amount of codeposited SiC nanoparticles between all samples produced by direct current electrodeposition.
