“…Such environments as highly polluted air, medium containing salts or chlorides are regarded as aggressive. The reason for low corrosion resistance of magnesium is insufficient protective properties of the layer of oxides that is formed on the surface in oxidizing atmosphere or the layer of hydroxides in water solutions [21][22][23][24][25][26][27][28][29][30][31][32].…”

The purpose of performed tests was evaluation of resistance to electrochemical corrosion of extruded magnesium alloy AZ31 with additive of 4.5% Li. Corrosion tests were performed in 0.01-2.0 M NaCl solutions. Potentiodynamic tests enabled to register polarisation curves. With application of stereoscopic microscope Nikon SMZ745T and electron scanning microscope Hitachi S-4200, the surface of the alloy was observed after immersion tests performed in 1-6 days. Results of performed tests prove explicitly deterioration of corrosion properties of the alloy with the increase of molar concentration of NaCl solution. It can be seen that corrosion process is intensive and that intensity increases with the increase of solution concentration and extension of exposure time.Keywords: magnesium alloy AZ31 with additive of 4.5% Li, electrochemical corrosion in NaCl, potentiodynamic test, immersion test, SEM
