Notes:
Magnesium and its alloys are possible to develop new type of biodegradable medicalmagnesium alloys by using their active corrosion potential. The bio-corrosion properties of the highpure magnesium in the Hank’s solution were investigated in this paper, the results showed that highpure magnesium had a low corrosion rate and hydrogen release in Hank’s solution, when the pH valueof solution was controlled at 7.5, the corrosion rate was under 0.2mm/year, the production of hydrogenwas about 0.15ml/cm2, and if the solution wasn’t controlled on pH value, the corrosion rate was about0.02 mm/year, production of hydrogen was about 0.1ml/cm2 . Result of in vitro Kinetic clotting timetest and animal implant prep-test showed that High pure magnesium had good thromboresistantproperty and tissue compatibility, pure magnesium can biodegrade lowly in animal body and formedsurface apatite, which proportion of Ca/P was similar with bone tissue
