AB  - Novel Zn-Co-CeO2 protective composite coatings were deposited successfully from chloride plating solutions. Two different types of ceria sources were used and compared: commercial ceria powder and home-made ceria sol. Electrodeposition was performed by a direct current in the range of 1-8 A dm(-2). Two different agitation modes were used and compared, magnetic stirring and ultrasound-assisted stirring (US). The influence of magnetic stirring on the stability of the related plating baths was evaluated via a dynamic scattering method. The results pointed to better stability of the prepared ceria sol. The morphology of the composite coatings was examined by scanning electron microscopy (SEM), and particle content was determined by energy-dispersive X-ray spectroscopy (EDS). The results showed that the increase in the deposition current density was not beneficial to the coating morphology and particle content. The corrosion behavior of the Zn-Co-CeO2 composite coatings was analyzed and compared by electrochemical impedance spectroscopy and polarization resistance. The ultrasound-assisted electrodeposition at small current densities was favorable for obtaining composite coatings with enhanced corrosion stability. The protection was more effective when US was applied and, additionally, upon utilization of ceria sol as a particle source, which was revealed by higher polarization resistance and greater low-frequency impedance modulus values for sol-derived composite coatings deposited under ultrasound.

AB  - The goal of this research was to develop and analyse novel Zn-Co-CeO2 protective coatings on steel. Two different sources of ceria (CeO2) particles were employed: commercial powder and synthesized stable colloidal dispersion-sol. The plating solution was agitated by ultrasounds (20 and 30 W cm(-2)) or by magnetic stirrer (300 rpm) during electrodeposition. The CeO2 particles used were characterized by different methods, namely scanning electron microscopy (SEM), transmission electron microscopy (TEM) and X-ray diffraction (XRD) to compare the morphology, crystallinity and particle size. The morphology of developed composite coatings was analysed by SEM, the preferred texture was calculated based on XRD results and corrosion behaviour was evaluated by electrochemical impedance spectroscopy (EIS) and polarization measurements. Utilizing ultrasounds during electrodeposition resulted in advanced properties of the nanocomposite coatings compared to magnetic stirring. The particle content in the coatings increased to similar to 5 wt% when ultrasounds were applied and ceria sol used as a source of particles. Presence of ceria in composite coatings offered favourable action in corrosion behaviour increasing barrier properties of composite coatings, thereby providing a prolonged lifetime of Zn-Co alloy coatings. The benefit was more pronounced in the case of ceria sol, and deposition at 20 W cm(-2), when values of impedance modulus at low frequencies reached four times higher values after 4 days exposure to 3 wt% NaCl solution than for coatings deposited with magnetic stirring for both ceria source. The lowest value of corrosion current density (2.15 mu A cm(-2)) was determined for Zn-Co-CeO2 (CeO2 sol) composite coatings deposited under 20 W cm(-2) US power.

AB  - Electrodeposition and characterization of novel ceria-doped Zn-Co composite coatings was the main goal of this research. Electrodeposited composite coatings were compared to pure Zn-Co coatings obtained under the same conditions. The effect of two ceria sources, powder and home-made sol, on the morphology and corrosion resistance of the composite coatings was determined. During the electrodeposition process the plating solution was successfully agitated in an ultrasound bath. The source of the particles was found to influence the stability and dispersity of plating solutions. The application of ceria sol resulted in an increase of the ceria content in the resulting coating and favored the refinement from cauliflower-like morphology (Zn-Co) to uniform and compact coral-like structure (Zn-Co-CeO2 sol). The corrosion resistance of the composite coatings was enhanced compared to bare Zn-Co as evidenced by electrochemical impedance spectroscopy and scanning Kelvin probe results. Zn-Co doped with ceria particles originating from ceria sol exhibited superior corrosion resistance compared to Zn-Co-CeO2 (powder) coatings. The self-healing rate of artificial defect was calculated based on measured Volta potential difference for which Zn-Co-CeO2 (sol) coatings exhibited a self-healing rate of 73.28% in a chloride-rich environment.
