| Summary: | Zinc (Zn)-composite coatings are still in demand as good corrosion barrier coatings to protect steel
substrates from corrosion environment. In this article, the Ni doped SnO2 nanoparticles were synthesized
and used as a composite additive for Zn-coating. The synthesis was carried out by the combustion
method using citric acid as a fuel. The Zn-Ni doped SnO2 composite coating was produced on mild steel
by an electroplating technique. The surface characterization and elemental analysis of the coated samples
were examined by X-ray diffraction spectroscopy (XRD), scanning electron microscopic images (SEM)
followed by energy dispersive spectroscopy (EDAX). The surface morphology of Zn-Ni doped SnO2
composite before and after corrosion showed a more compact surface structure with respect to the pure
Zn-coat. The corrosion resistance property of the Zn-Ni doped SnO2 composite coating was studied by
Tafel polarization and electrochemical impedance spectroscopy. |
