Embodiment 1

[0040] First, pure Zn ingot (99.99wt.%), single crystal Ge (99.999wt.%), pure Mg ingot (99.95wt.%) were used as raw materials, and according to the composition of the three elements in the ternary Zn-3Ge-0.5Mg alloy composition The mass ratio is weighed. Then put pure zinc into a graphite crucible and place it in a pit furnace for melting. 2 Under the protection of the atmosphere, heat to 550°C for smelting. After the pure zinc is completely melted, add single crystal Ge, and press the single crystal Ge into the liquid surface to avoid the phenomenon that Ge cannot be melted due to floating up. After the single crystal germanium is fully melted, the pure Mg ingot is pressed into the liquid surface, and the temperature is adjusted to 540°C. After the pure Mg ingot is completely melted, continue to stir with a graphite rod for 2 minutes, and then carry out slag removal after standing for 5 minutes, and lower the pouring temperature to 520°C. Finally, it is poured into a steel ...

Embodiment 2

[0057] Firstly, pure Zn ingot (99.99wt.%), single crystal Ge (99.999wt.%), pure Cu wire (99.99wt.%) were used as raw materials, and according to the composition of three elements in the ternary Zn-3Ge-0.5Cu alloy The mass ratio is weighed. Then put pure zinc into a graphite crucible and place it in a pit furnace for melting. 2 Under the protection of the atmosphere, heat to 590°C for smelting. After the pure zinc is completely melted, add single crystal Ge, and press the single crystal Ge into the liquid surface to avoid the phenomenon that Ge floats up and cannot be melted. After the single crystal germanium is fully melted, press the pure Cu wire under the liquid surface, and adjust the temperature to 550°C. After the pure Cu wire is completely melted, continue to stir with a graphite rod for 5 minutes, and then carry out slag removal after standing for 10 minutes, and lower the pouring temperature to 520°C. Finally, it is poured into a steel mold preheated to 220°C, and a...

Embodiment 3

[0062] First, pure Zn ingot (99.99wt.%), single crystal Ge (99.999wt.%), pure Fe powder (99.99wt.%) are used as raw materials, and according to the composition of three elemental elements in the ternary Zn-2Ge-0.7Fe alloy composition The mass ratio is weighed. Then put pure zinc into a graphite crucible and place it in a pit furnace for melting. 2 Under the protection of the atmosphere, heat to 640°C for smelting. After the pure zinc is completely melted, add single crystal Ge, and press the single crystal Ge into the liquid surface to avoid the phenomenon that Ge floats up and cannot be melted. After the single crystal germanium is fully melted, the pure Fe powder is pressed into the liquid surface, and the temperature is adjusted to 600°C. After the pure Fe powder is completely melted, continue to stir with a graphite rod for 2 minutes, and then carry out slag removal after standing for 5 minutes, and lower the pouring temperature to 550°C. Finally, it is poured into a ste...

Abstract

The invention discloses a Zn-Ge-X ternary biomedical material and a preparation method thereof. The Zn-Ge-X ternary biomedical material comprises the following components in percentage by mass: 0.5-6wt% of Ge, 0.1-1wt% of X and the balance of Zn, wherein X is selected from at least one of Mg, Cu, Mn, Sr, Fe, Ca, Ag and Ti. The ternary Zn-Ge-X biomedical material prepared by adopting traditional casting and deformation treatment as the preparation method and through optimizing deformation treatment and the components of the ternary material has excellent mechanical properties, good cell compatibility and suitable biodegradability, and is expected to become a potential degradable biomedical material.

Description

technical field [0001] The invention relates to a Zn-Ge-X ternary biomedical material and a preparation method thereof, belonging to the field of biomedical metals. Background technique [0002] With the development of the biomedical field, the application of biodegradable biometal materials in medicine is very common. After this kind of material is implanted into the human body, it first replaces the tissue at the wound site to perform functions, and then as the material degrades and absorbs, the new tissue is replaced synchronously, and finally achieves the purpose of permanent treatment, eliminating the risk and pain of secondary surgery. Greatly improved the curative effect. In addition, biodegradable biometal materials have high tensile and compressive strength, excellent ductility and impact resistance, stable mechanical properties, high reliability, and excellent forming and processing performance after implantation. According to the individual needs of patients, It...
