Abstract
Evaluation of the corrosion behavior of commercially pure magnesium (CP-Mg) and ZM21 Mg alloy
immersed in Ringer’s solution for 92 h by electrochemical impedance spectroscopy (EIS) is addressed.
The formation of a compact layer of well-developed rod-like aragonitic CaCO3 crystals and its subsequent
thickening with increase in immersion time offers a higher corrosion protective ability for ZM21 Mg
alloy. The formation of a mud-crack pattern and a large number of clusters of needle-like crystals offers
a relatively lower corrosion resistance for CP-Mg. The study suggests that ZM21 Mg alloy is a promising
candidate material for the development of degradable implants.
