In this study, corrosion behaviour of β-Mg17Al12 phase was studied as comparing pure magnesium. The corrosion tests were carried out by potentiodynamic polarisation measurements and immersion tests in 3.5 wt% NaCl solution. Compared to pure Mg, β-Mg17Al12 phase has 2.7 times and 2.1 times lower corrosion resistance according the potentiodynamic polarization and immersion test results, respectively. Deep corrosion pits were formed on the surface of the β phase.
