Anti-Corrosion and High Temperature Thermal Treatment of SiO2 Crystal Induced on Zinc Electrolyte on Mild Steel

Abstract

The effects of SiO2 nanoparticles on the electroplating of Zn–Nb2O5 coatings of mild steel were considered in this research work. The hardness performance and corrosion resistance of the coated samples were analysed using Emco-test microhardness tester and Autolab PGSTAT 101 Metrohmpotentiostat/galvanostat. The results of the research showed that Zn–10Nb2O5–SiO2 coatings displayed preferable hardness property and corrosion resistance compared to Zn–10Nb2O5 coating. Also, the incremental addition of SiO2 nanoparticles improved the hardness behaviour and corrosion resistance of Zn–10Nb2O5 coatings.
