- •
Corrosion of high purity (HP) Mg, AZ91 and ZE41, was studied in CO2-bicarbonate buffered Hanks solution.
- •
Corrosion rates were in the following decreasing order: ZE41 > HP Mg > AZ91.
- •
All corrosion rates decreased slightly with increasing pH, attributed to more stable protective films.
- •
A slow fluid flow caused a slightly higher corrosion rate and a more-uniform corrosion morphology.
