2008 m. Nr. 1 Effect of pulse plating on the composition and corrosion properties of Zn–Co and Zn–Fe alloy coatings
The influence of pulse plating parameters on the chemical and phase composition, surface topography and corrosion resistance of Zn–Co (<1%) and Zn–Fe (<1%) alloy coatings has been studied. Pulse plating of low-alloyed Zn coatings resulted in the grain size reduction of deposits, however, this process was not accompanied by any significant reduction in the corrosion currents of these alloys. It was suggested that the dual phase formation was the principal reason why pulse plated low-alloyed Zn coatings did not exhibit any improvement in their corrosion resistance. Keywords: pulse electrodeposition, zinc alloys, phase composition, corrosion |
