Abstract

The Authors have studied and compared the surface properties of mild steel with barrier layers of zinc, Zn + 3%Al, Zn + 3%Al + 1% misch metal + 1.5% SiC, and other different compositions. The electrochemical parameters like weight loss, corrosion rate, icorr and open circuit potential values were obtained in 0.04N NaOH solution with 0.09% NaCl. Impedance values were also obtained. Specimens were evaluated in salt spray cabinet for their performance. The layer composition Zn + 3%Al + 1% misch metal + 1.5% SiC, revealed superior electrochemical properties. The thickness of the barrier layers, was determined and the photomicrographs of the cross section reported
