dc.description.abstractNi-P-TiO2 composite coatings are important in engineering due to their properties such as good resistance to wear and corrosion, magnetic properties, electrical and thermal conductivity. In this paper, the effect of current density on electrodeposited Ni-P-TiO2 composite coatings was investigated for the first time. Ni-P-TiO2 composite coatings were deposited with applied current densities (1, 3, 5, 7 and 9 A·dm – 2) on copper substrates. X-ray diffraction (XRD) analysis, scanning electron microscopy (SEM), energy dispersive spectroscopy (EDS) and microhardness analysis were used to study the morphological, microstructural and mechanical properties. On the other hand, the corrosion performance of the coatings was evaluated using Tafel polarization and electrochemical impedance spectroscopy (EIS). XRD results indicate that the inclusion of TiO2 nanoparticles into the coatings alters the relative intensity of Ni peak as well as peak breadth. In addition, microhardness of the coatings noticeably increased with current densities. Ni-P-TiO2 composite coating electrodeposited at 3 A·dm – 2 exhibits the best microhardness and corrosion resistance.
