“…Corrosion potential of nanocomposite coatings are nobler than those of Zn-Ni ones, which is in good agreement with the study of Katamipour et al [57] The surface ennoblement can be due to a screening effect induced by ceria particles, which can block some defects of the coatings. [58] Concerning the corrosion kinetics in the anodic domain, a slight modification after one hour of immersion is observed when particles are incorporated.…”

Pure Zn‐Ni and Zn–Ni–ceria (CeO2) nanocomposite coatings were deposited onto steel substrates using pulse electrodeposition process from an acidic bath combined with preliminary sonication. Influences of different parameters such as pulse parameters, addition of nanoparticles in the electroplating bath, use of sonication to ensure their dispersion, were studied in terms of morphology, composition, and corrosion behaviour in saline solution. Results revealed a strong influence of the electrodeposition parameters on the corrosion behaviour of the Zn‐Ni coatings. Incorporation of ceria nanoparticles is enhanced for the very short duration of the pulse due to the refinement of the microstructure. It was proved that composite coatings present an enhanced corrosion behaviour, while sonification does not afford a further improvement.

“…Electrodeposition of composite coatings for the production of metal matrix composites is composed of a metal matrix electrolyte and dispersed second phase particles (Yang et al, 2009). Incorporating a great variety of particles, such as hard oxides and carbides (SiO2, Al2O3, TiO2, CeO2, SiC, and WC), solid lubricates (PTFE, Graphite, and MoS2), multiwall carbon nanotubes, graphene, and diamond, into the metal matrix have been used to enhance the lifetime, performance, corrosion resistance, wear resistance, and hardness of the metal matrix composite coatings (Katamipour et al, 2014;Lia et al, 2016;Thurber et al, 2016).…”

In this paper, Ni-TiO2 nanocomposite coatings with different sizes of TiO2 nanoparticles were successfully prepared by electrodeposition process from a nickel electrolyte in which the TiO2 nanoparticles were suspended. The influence of relevant deposition parameters on the nanocomposite coating characteristics was discussed. X-ray diffractometer has been applied in order to investigate the phase structure of the nanocomposite coatings. The surface morphology of nanocomposite coatings was characterized by a scanning electron microscopy equipped with an energy dispersive spectroscopy. The electrodeposited nanocomposite coatings obtained at different deposition parameters were evaluated for their mechanical and corrosive properties. Obtained results show that the size of TiO2 nanoparticles and applied current density during deposition process has a direct effect on mechanical and corrosive properties of nanocomposite coatings. Increasing current density and smaller nanoparticle size has affirmative effect on mechanical properties, whereas corrosion resistance of nanocomposite coatings deposited at 3 A dm −2 current density are higher than the coatings prepared at higher current density values.

The aim of this work was to obtain composite of nc-TiO 2 /Ni coatings on 316L steel and to characterize their corrosion resistance. In order to investigate the influence of the addition of TiO 2 nanoparticles, both pure Ni and composite nc-TiO 2 /Ni coatings were electrodeposited from nickel citrate baths. The microstructure of the coatings was examined by scanning and transmission electron microscopy. The nc-TiO 2 /Ni coatings were about 10 μm thick. Their microstructure consisted of TiO 2 nanoparticles uniformly distributed in nanocrystalline Ni matrix. The corrosion resistance of the coatings was measured using impedance spectroscopy and polarization curves techniques in Ringer's solution. It was determined that the addition of nano-TiO 2 particles improved corrosion resistance and reduced corrosion rate of the coated steel.
