The paper offers an analysis of the fluoride conversion coating prepared on ZE10 magnesium alloy with the aim to improve material corrosion properties with respect to the biocompatibility of the alloy. The coating was prepared via unconventional process, by immersion of the alloy in Na[BF4] molten salt at 430 and 450 °C for various treatment times. The coating was analysed in terms of scanning electron microscopy, energy dispersive X-ray spectroscopy and electrochemical impedance spectroscopy. The coating was shown to be compact and homogenous with intermetallic particles incorporated in the coating. Significantly higher values of the polarization resistance were estimated for the coated specimens when compared to the untreated ZE10 alloy in simulated body fluid solution at 37 ± 2 °C.Keywords: Wrought ZE10 magnesium alloy, fluoride conversion coating, corrosion, electrochemical impedance spectroscopy.
