Abstract: Surface modification is an effective method to improve the corrosion resistance of pure magnesium and its alloys. In this paper, a NaMgF3 film was formed on pure magnesium surface by immersing the substrate in the solution with 4wt% NaF and different amounts of glacial acetic acid solution in distilled water at room temperature. The effect of glacial acetic acid concentration and immersion time on the film quality was studied. Scanning electron microscope (SEM), X-ray diffraction (XRD) and energy dispersive spectrometer (EDS) were used to analyses the morphology and crystal structure of the film. The corrosion resistance of pure magnesium before and after surface modification was investigated by electrochemical tests and immersion experiments in simulated body fluid (SBF). The optimal acetic acid concentration and immersion time were found to be 5vol% and 8 h, respectively. The NaMgF3 film was compact and uniform, composed of cubic particles with the size of about 0.3 μm. As compared with the substrate, the corrosion potential of coated magnesium was increased by 740 mV, and the corrosion current density reduced by 2 orders of magnitude. Also, a smoother corrosion product layer formed in SBF.
