| Abstract Scope |
Superior biocompatibility and biodegradability of Mg based alloys make them an excellent choice for orthopedic implants such as stents and screws. Furthermore, they can lessen the stress shielding effect and abandon the secondary post-healing surgery requirements. The present study establishes a processing-structure-property–correlation of Mg-Zn-Si-xSn alloys (x= 0, 1, 2, 3, 4 wt.%). Alloys were produced by two different ways: pressure die casting and gravity die casting. SEM in conjunction with EDS, XRD, and EBSD were utilized for microstructural characterization. Following that, bulk compression testing, and Vickers hardness (HV) testing were used to determine the mechanical properties. In addition to that, the corrosion behavior of these alloys was examined using potentio-dynamic polarization test, hydrogen evolution test and weight loss measurement in HBSS (Hanks Balance Salt Solution) to determine their biocompatibility. It has been deduced that changes in Sn percentage have a significant impact on both corrosion and mechanical properties. |
