摘要：
Magnesium, AZ91 alloy and composite materials AZ91/SiC undergo active dissolution in Ringer solution at 36,7 degrees C. The corrosion resistance of AZ91 magnesium alloy is determined by beta-Mg17(Al, Zn)(12) phase. This phase easily undergoes the passivation, hence hinder the corrosion process of AZ91 alloy. However, the presence of SiC in composite AZ91/SiC does not have essential influence on its corrosion resistance in Ringer solution compare to corrosion resistance of AZ91 magnesium alloy.
