The effect of current density on electrochemical magnesium phosphate of low carbon steel and its corrosion resistance — •Mohammadreza Dayyari and Sina Sadreddini — Department of Materials Science and Engineering, Science and Research Branch, Islamic Azad University, Tehran, Iran.

In this study, the magnesium phosphate coating was electrodeposited on aluminum at different current densities. Various current densities were applied to investigate the effect of current density on thickness, surface morphology and corrosion behavior. The related morphology was investigated by scanning electron microscopy (SEM) and crystalline structure was examined by X-Ray diffraction (XRD). The corrosion behavior was evaluated using electrochemical impedance spectroscopy (EIS) and polarization techniques.The results showed that by applying magnesium phosphate coating, the Newberyite structure was formed in the coating structure and at a current density of 5mA/cm2, finer morphology, reduced porosity and increased corrosion resistance were observed.
