Magnesium and its alloys have gathered lot of interest as suitable candidates for orthopedic implants and fixing accessories, due to, biodegradability, non-toxicity and mechanical properties, similar to natural bone. The major drawback of magnesium is its low corrosion resistance inside living body, which also influences its mechanical and physical characteristics in service condition. The aim of the present study is to develop a Mg based material system to be used as bone fixing accessories, e.g. screw, nail, plates etc. We achieved that by fabricating composites of Mg and hydroxyapatite (HA). The composite is fabricated through powder consolidation route. The in vitro bio–corrosion (biodegradability) and mechanical behaviors of samples are investigated by electrochemical and compression tests. The experimental results showed that addition of HA could slow down the corrosion rate and improve the mechanical properties of biodegradable magnesium alloy. Biocompatibility of the composites also improves with addition of HA.
