The phosphatepermanganate conversion coating was prepared on the surface of experimental alloy to improve corrosion resistance. This conversion coating was prepared like alternative to the chromating process which proved greatly results on magnesium alloys. Nevertheless, the use of chromates is limited by the environmental regulations in Europe. The corrosion resistance of extruded AZ61 magnesium alloy with and without conversion coating was tested by immersion test. The samples were immersed in sodium chloride solution (3.5 %) with immersion times 1, 8, 48 and 168 hours. The weight losses were measured at analytical balances (d = 0.1 mg) and expressed as corrosion rate in [mm year-1]. Microstructure, surface morphology of conversion coating and corrosion attack were observed by light and scanning electron microscope."@en . "Koroze a ochrana materi\u00E1lu.
