- Аннотация: The evolution of the microstructure and mechanical properties of biodegradable alloys Mg-3SN-1ZN-0.5 million was studied using optical microscopy, X-ray diffraction, and universal material testing. Corrosion and degradation behavior were investigated using potentiodynamic polarization and immersion testing in simulated body fluid (SBF). It was found that the alloy with AS-3SN-1ZN-0.5 million has fine equiaxed grains that underwent complete dynamic recrystallization during hot extrusion, with the second phase of MG2SN particles precipitated at grain boundaries and within grains. The tensile strength and elongation of As-Extruded Mg-3SN-1ZN-0.5 million alloys were 244 ± 3.7 MPa and 19.3% ± 1.7%, respectively. The potentiodynamic polarization curves in the SBF solution indicated better corrosion resistance of the As-Extruded Mg-3SN-1ZN-0.5 million alloy in the SBF solution. Immersion testing in the SBF solution for 720 hours showed that the corrosion rate of the As-extruded Mg-3SN-1ZN-0.5 million alloy was nearly 4 ± 0.33 mm/year. The hemolysis rate of the Mg-3SN-1ZN-0.5 million alloy was below the safe value of 5% according to ISO 10993-4. The As-Extruded Mg-3SN-1ZN-0.5 million alloy showed good biocompatibility after implantation in the dorsal muscle and femoral vein of rabbits, and no abnormalities were found after short-term implantation. It was revealed that the Mg-3SN-1ZN-0.5 million alloy is a promising material for biodegradable implants, possessing an interesting combination of desirable mechanical properties, better corrosion resistance, and biocompatibility.
