Abstract
The electroplating of ternary Zn–Ni–Co alloy, the influence of cobalt codeposition on crystal orientation, surface topography and corrosion resistance were investigated and contrasted with the characteristics of Zn–Ni electrodeposits. It was found that the Zn–Ni–Co alloy showed better corrosion resistance, in 3% sodium chloride, in comparison with Zn–Ni alloy electroplated under similar conditions. The best corrosion resistance was observed for ternary deposits having 11.24% Ni and 6.52% Co. The crystal orientation and surface topography were characterized by means of X-ray diffraction analysis and scanning electron microscopy, respectively.
