Fabrication and Characterization of Ni-TiO₂ Nanocomposite Coatings and Their Corrosion Resistance Behaviors

Abstract:

Ni-TiO₂ nanocomposite coatings have been successfully fabricated via a route electrodeposition from nickel Watts bath containing nano-TiO₂ particles, and characterized by scanning electron microscopy (SEM),X-ray diffraction(XRD), energy dispersive X-ray spectroscopy (EDS)and electrochemical techniques. The influence of preparation parameters on the properties of the coatings were investigated. The obtained results indicated that nano-TiO₂ particles were distributed uniformly in the Ni matrix. It was found that the Ni-TiO₂ nanocomposite coatings exhibited more excellent corrosion resistance and microhardness in comparison with pure nickel coating.
