Abstract:

The development of biodegradable biomaterials used in the medical industry represents a crucial aspect in the evolution of therapeutic medical techniques and methods. This research focuses on the microstructural characterization of alloys within the Mg-Ca-Sr system, which includes five distinct formulations composed primarily of magnesium with a fixed 0.5% calcium content and strontium varying from 0.5% to 3%. The alloys were cast in ceramic crucibles utilizing an induction furnace under an inert argon atmosphere to minimize oxidation and eliminate the flammability hazards inherent to magnesium-based materials. Microstructural evaluation was performed using both optical microscopy and scanning electron microscopy, demonstrating homogeneous microstructures free of porosity. The use of these types of biomaterials can foster new directions in implantation, both in orthopedics and maxillofacial medicine.


Keywords: Magnesium alloy, microstructure, biomaterials, analysis, medical applications.
