Abstract
Using potentiodynamic polarisation, polarisation resistance and electrochemical impedance spectroscopy measurements, the effect of amide treatment to magnesium metal matrix composite in 0·6 N sodium chloride medium has been studied. The corrosion potential Ecorr, corrosion current Icorr, polarisation resistance Rp and charge transfer resistance Rct were determined from the corresponding plots. Ecorr shifted towards more negative values while Icorr decreased with increasing treatment time. Surface analysis with SEM and AFM showed an improvement in surface due to formation of a film. X-ray diffraction (XRD) and Fourier transform infrared spectroscopy (FTIR) studies confirmed the film formation and the coordination of magnesium to the oxygen in the amide compound.
