Magnesium is one of the lightest structural metals with high specific mechanical properties and good biocompatibility making them an ideal candidate for biomedical implants. Mg has high corrosion rate in aqueous medium and presence of chloride ions leading to premature loss of mechanical properties. In the present work, a Mg-Zn-RE-Zr (EZ33) alloy is subjected to friction stir processing (FSP) and is evaluated for in vitro corrosion response. The Mg alloy subjected to FSP results in refined grains with fine distribution of the secondary precipitates. The refined grains help in obtaining higher mechanical properties and distribution of the precipitates help in the corrosion response. The processed alloy is studied for in vitro corrosion response in Hanks balanced salt solution maintained at 37±1°C to simulate human body conditions. Results from present study can help in microstructure engineering of Mg alloys with tailorable mechanical and corrosion properties for biomedical applications.
