Abstract

EN24 Steel is found to be more reliable and used in majority of automotive applications, the corrosion problem of it disappoints the motorists due to its reduced life. This problem can be overcome by coating possible metals on the metal substrates and studying their corrosion behaviour. In this study, Ni is coated on EN24 steel and their corrosion behaviour is studied and compared with that of unplated one. The corrosion behaviour of nickel plated EN24 steel investigated in 3.5 wt% of Sodium chloride solution at room temperature. This study was done by electrochemical potentiodynamic polarization method. Using the scanning electron microscope (SEM) Surface morphology was done. The corrosion rate of nickel plated EN24 materials decreased with increase in certain range of plating thickness. However, Ni plating has proved to be an effective barrier against corrosion.
