| dc.description | The construction industry is faced with challenges arising from corrosion leading tostructural deformation and pitting evolution of mild steel. This involved water and saltsolutions forming electrolytes resulting in corrosion products. The struggle has been toprovide special; desirable properties inform of coating to offer dependable service life formild steel. This study seeks to assess the effects of deposition time of Ni-P-Zn-Si3N4coatings on mild steel. The coatings were developed using direct electrolytic bathtechnology with constant particle concentration of silicon nitrides and different timevariables. The effect of the deposition time on the substrate was assessed byelectrochemical study via potentiodynamic polarization. Scanning electron microscopeequipped with energy dispersive spectroscopy (SEM/EDAX) and optical microscopy wasused to study the surface modification on the mild steel. It was found that deposition timeaffected the coating film formed and the influence of incorporating the Si3N4phase into Ni-P-Zn series was seen to cause perfect nodularity and second phase crystals, especially withNi-P-Zn-Si3N4nanocrystalline deposited at 10 min. This was further established by thelinear and open circuit polarization with less corroded products seen at the steel interface | |
