Abstract In this research, Mg–3Zn–xSi (x = 0, 0.1, 0.3, and 0.6 wt%) biodegradable alloys were produced by simple stir casting method, their microstructure phase changes evaluated using X-ray diffraction (XRD), optical microscope (OM) scanning electron coupled with energy dispersive x-ray analysis (SEM–EDS). Potentiodynamic polarization was conducted to measure the alloys’ corrosion behavior in simulated body fluid (SBF). Tensile strength test in-vitro biocompatibility evaluation regarding MTT cytotoxicity, ALP osseointegration assay MG-63 cell growth pattern conducted. Electrochemical investigations showed that Mg–3Zn enclosing Si attained degradation rates suitable for structural support until bone healing, while alloy without had a rate of 0.128 mm/year which is much lower than required value. None inspected exhibited significant cytotoxic effect, meanwhile, Mg–Zn base 0.3 wt% demonstrated highest level. The optimum 0.1 Si. Evidence calcium phosphate precipitation observed four investigated alloys. Therefore, based on fore mentioned results, suggested as viable materials due compatible rates, proved cytocompatibility, high viability excellent potential.

Magnesium (Mg) based materials show great promise as temporary implant applications owing to their biocompatibility and biodegradability. These characteristics remove the risk of subsequent surgery extract once process bone tissue healing is finished. Additionally, its density elastic modulus are near those natural bone, thereby reducing stress-shielding effect. Mg mostly recognized for osteoconductive abilities, which implies that it encourages generation fresh tissue. It also has antimicrobial properties, lower possibility infections leading failure. Moreover, rapid bio-corrosion pure in presence physiological fluids a serious concern. The implant's mechanical integrity deteriorates result this corrosion before surrounding completely recovered. To address these issues, review focused on approaches, including alloying, creation composites, surface coating, can increase biomechanical properties.

The chemical composition in depth profiles, morphological structural characteristics the on Zn/Mgt (labeled as Zn-Mn/(Zn/Mgt)) analyzed using Glow Discharge Optical Emission Spectroscopy (GD-OES), Scanning Electron Microscopy/Energy Dispersive X-ray spectroscopy (SEM/EDS), diffraction (XRD). When manganese content was greater than 0.19 wt.%, results reveal formation two phases: η-ZnMn ζ-MnZn13; while ζ-MnZn13 phase favored increasing alloy. On other hand, microhardness, wear resistance, coefficient friction significantly increase when coating substrate corrosion performance this evaluated potentiodynamic polarization, electrochemical impedance (EIS). degradation rate Hank's solutions pristine (0.29 mm yr-1) decreases due to coating. Furthermore, further decreased from 0.051 0.022 yr-1, varying amount 0.26 respectively. However, increases up 0.064 yr-1 at higher content, Mn.
