In this study, magnesium phosphate coating was applied to low carbon steel via electrochemical method, its morphology was examined by scanning electron microscopy (SEM) and its crystalline structure was investigated by X-ray diffraction (XRD). Corrosion behavior of coated samples was evaluated by electrochemical impedance spectroscopy (EIS) and polarization techniques.
The results showed that the application of magnesium phosphate coating significantly improved corrosion resistance behavior by forming Newberyite phase.
