Fe–Ni composite coatings reinforced with SiC nanoparticles and carbon nanotubes: corrosion and tribological performance

The fabrication of electrodeposited Fe-Ni composite coatings reinforced by SiC nanoparticles and multi-wall carbon nanotubes (MWCNT) separately was studied in this research. For this aim, the electrodeposition method was performed in a sodium chloride bath at a current density of about 10 A dm −2 . The specimen’s phase and microstructure was investigated by XRD and SEM analysis, respectively. The wear and corrosion performances of coatings were also inspected using pin-on-disk (at ambient atmosphere) and Potentiaodynamic test techniques, respectively. The results point out that the electrodeposition method can be used to deposit Fe-Ni composite coatings containing SiC and CNT on a steel substrate. The results show that the presence of SiC nanoparticles in the coating matrix caused an improvement in the corrosion resistance of this coating as compared to that of Fe–Ni coat. Furthermore, MWCNT have significant effects on decreasing the friction coefficient and enhancing the wear resistance of the Fe-Ni coating.
