Beschreibung
Zusammenfassung:	The invention discloses a Zn-K series degradable zinc alloy with biological activity and a preparation method of the Zn-K series degradable zinc alloy. The Zn-K series degradable zinc alloy contains 0.05-3.0 wt.% of K, is prepared through a method of ingot prefabrication and remelting, and can be applied to preparation of orthopedic implantation instruments and bioactive membranes/patches. The Zn-K series degradable zinc alloy is controllable and adjustable in corrosion degradation rate, excellent in biological performance, capable of promoting tissue repair, capable of being completely degraded and absorbed and suitable for various clinical scenes. 本发明公开了一种具备生物活性的Zn-K系可降解锌合金及其制备方法。所述Zn-K系可降解锌合金含有0.05-3.0wt.％K，通过"预制锭+回炉重熔"的方法制备得到，可应用于制备骨科植入器械和生物活性膜/补片。本发明的Zn-K系可降解锌合金的腐蚀降解速率可控可调，生物学性能优异，可促进组织修复，可被完全降解吸收，适用于多种临床场景。
