Abstract

See full text

Disclosed is a degradable zinc base alloy implant material comprising, by mass percentage content, 0.01 wt % to 14 wt % of Fe, 0 wt % to 13 wt % of functional elements and the remainder being Zn and a preparation method and use thereof. During preparation, Zn, Fe, and the functional elements are homogeneously mixed and placed into a high-purity graphite crucible and smelted together under a mixed gas atmosphere of SF6 and CO2. The mechanical properties of the zinc base alloy implant material have been significantly improved, so that the implant material is easy to process and shape, and so that the properties of strength and plasticity, etc., meet the basic requirements of human body implant materials, such as vascular stents, orthopedic internal fixation systems, and the like.
