Özet
The surface of magnesium electrode was coated by immersing in phosphate, tungstate, molibdate and cerium solutions, after polishing with sand paper and abrading in 0.15 M HCl solution for 20 seconds. The corrosion of modificated magnesium with different compounds was investigated by electrochemical methods in 1 M NaCl solution. The results show that phosphate, tungstate, molibdate and cerium cations provide the corrosion protection for magnesium forming insoluble compounds on magnesium surface. The inhibition effect of protective layers prepared on magnesium surface were investigated by using potential-time, current-potential curves and Electrochemical Impedance Spectroscopy (EIS) spectra. The inhibition effect was calculated from corrosion rates and polarization resistance. © Pleiades Publishing, Ltd., 2012.
