الملخص الإنجليزي

Three groups of heat treated AZ31 Magnesium alloy was used to do this research.

First group was the base group which are used as received samples, second one was the recrystallization annealing samples and the third group was solution treated samples.

Wear test was carried out by sliding the specimen on the bone surface in Nutritious water with constant speed at different times.

A bio-corrosion test was accomplished for three groups by immersing the specimen in Hank's solution and measuring the corrosion rate for each group by Electrochemical Impedance Spectroscopy (EIS) and Tafel test.

The result from wear test show the wear resistant of solution treatment group are the lowest.

The result from corrosion test show high corrosion rate in as received specimen and low corrosion rate in recrystallization annealing specimen while the solution treated specimen are between them.

The corrosion properties are dependent on patients state, if the fractured part needs longer time to heal, so we should use recrystallization annealing state, and if the fractured part need low or moderate time to heal we should be used as received or solution treated state respectively.
