Özet

In this study, corrosion behaviour of β-Mg17Al12  phase was studied as comparing pure magnesium. The corrosion tests were  carried  out  by  immersion  tests  and  potentiodynamic  polarisation  measurements  in  3.5%  NaCl  solution. Compared to pure magnesium, β-Mg17Al12 phase has 2.7 times and 1.8 times lower corrosion resistance according the  potentiodynamic  polarization  and  immersion  test  results,  respectively.  Hardness  test  was  also  showed  that  β -Mg17Al12 phase was 3.4 times harder than pure magnesium.
