Abstract EN
The aim of this research work was to codeposit nano-SiO2 particles into Zn-Ni alloy coatings in order to improve some surface properties.
It had been investigated the effect of loading the plating bath with nanoparticles on composition, morphology, phase structure of deposits, and their subsequent influence on the corrosion process in corrosive solution of 3% NaCl and the thermal stability of deposits at 200°C.
It was found that Zn-Ni alloy composites contain a higher percentage of Ni with incorporation in the deposit of 1.54% of silica.
X-ray diffraction measurements revealed that the alloys consisted of two phases, pure zinc and γ phase.
Electrochemical characterization of the composites had been carried out through potentiodynamic polarization and electrochemical impedance spectroscopy.
The composites exhibited higher values of microhardness and better corrosion resistance in corrosive media.
