Investigating Electrochemical Inhomogeneity on Phosphating Process of Nano-SiO2 Additive Using Wire-Beam Electrode

Abstract

In this paper, nanoSiO2used to be an accelerator of Zinc phosphatization for electrochemical inhomogeneity in the process of phosphate coatings on carbon steel by wire-beam electrode. The open circuit potential of the phosphated samples was analyzed using average method. The result showed the large influence of nanoSiO2on the nucleation and growth of the phosphate coatings.
