More Information
Summary:The invention belongs to the technical field of biomedical materials, and particularly relates to a biomedical degradable Mg-Gd-Nd-Zn-Zr alloy, and a preparation method and application thereof. The alloy is composed of the following components in percentage by weight: 2-7% of Gd, 0-2% of Nd, 0.1-1% of Zn, 0.1-0.5% of Zr, and the balance of Mg and inevitable impurity elements. The preparation method comprises the following steps: proportioning, and sequentially smelting Mg, Zn, an Mg-Gd interalloy, an Mg-Gd interalloy and an Mg-Zr interalloy under protective atmosphere conditions; and after finishing smelting, adding a refining solvent, refining, and finally, casting to obtain the biomedical degradable Mg-Gd-Nd-Zn-Zr alloy. The alloy has favorable biocompatibility and mechanical strength, and can be used for preparing vessel stent medical materials.
