【 摘 要 】

Authors elaborated a five component material using specific magnesium master alloys with several elements resulting a potential biocompatible and biodegradable alloy. The main goal of the present paper is to investigate the properties of some master Mg-2Ca-0.2Mn-0.5Zr-1Y alloy. The surface morphology was characterized using X-ray diffraction (XRD), optical microscopy and scanning electron microscopy (SEM). After the XRD analysis, it have been identified the following compounds, such as Mg, Mg2Ca, Mg24Y5, respectively MgY. These compounds have the hexagonal crystallographic structure for Mg and Mg2Ca type, respectively cubic form for Mg-Y and Mg24Y5. The microstructure presents a uniform morphology and an undisclosed zirconium. Also, manganese is embedded in magnesium and Ca forms a lamellar eutectic mixture of Mg2Ca type. In conclusion, Mg-2Ca-0.2Mn-0.5Zr-1Y alloy shows similar characteristics from the microstructure point of view with other biodegradable materials, these alloy could be used as biodegradable implant.
