The Mg-6%Zn-5%Hydroxyapatite (HA) biomaterial had been prepared through powder metallurgy method in this investigation. The mechanical properties and biodegradable behaviors of the Mg-Zn-HA composite in simulated body fluid were studied. The Mg-Zn-HA specimens obtained appropriate density, adjustable elastic modulus and compatible strength to natural bones. Immersion corrosion experiments revealed that 5wt% addition of HA in Mg-6%Zn alloy exhibited acceptable corrosion rates in simulated body fluid. The Mg matrix, Mg7Zn3 phase and HA are identified in the experimental composite. The Mg(OH)(2) and Hydroxyapatite were found on the corrosion products in the simulated body fluid.
