Özet

In this study, corrosion behaviour of beta-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, beta-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 beta phase.
