Abstract:

 


The influence of the Al content and associated β
morphology on the corrosion of Mg alloys has been studied using AZ41 and AZ91
series Mg alloys and compared with the corrosion of non Al containing Mg alloy
(i.e AZ01). Scanning
electron microscopy (SEM) was used for microstructural examinations. The
corrosion behaviors were evaluated by immersion tests and potentiodynamic
polarization measurements in 3.5% NaCl solution. The globular shaped β
intermetallic phases were present in AZ41 alloy whereas they were transformed
into a more coarsened lamellar or partially divorced β eutectics in AZ91
alloys. The results
showed that the influence of Al addition on corrosion resistance was more
pronounced up to 4 wt% (i.e AZ41) above which its influence was at less extent.
The deterioration of the corrosion resistance of the alloys, at higher Al
contents, was attributed to amount and morphology of β (Mg17Al12) intermetallics
and the interruption of continuity of the oxide film on the surface of the
alloys owing to coarsened β intermetallics.
