摘要

基于多元少量的合金化原则，在Mg中添加了Y、Nd、La、Ce等稀土元素及Zr元素，制备生物可降解镁合金。测试了镁合金的力学性能和腐蚀性能。结果表明，Mg-Y-Nd-(La+Ce)-Zr合金在Nd含量为2.7%

Y含量为4.2%

La+Ce含量为0.1%

Zr含量为0.5%时，抗拉强度达到223 MPa

力学性能较好，且在Hank’s溶液中腐蚀96 h后的平均腐蚀速率为0.209 mg/(cm~2·h)。

Abstract

Based on the principle of multi-element and small amount of alloying

rare earth elements such as Y

and Zr were added to Mg to prepare a novel magnesium alloy

and the mechanical properties and corrosion properties were measured. The results show that the tensile strength of Mg-Y-Nd-（La+Ce）-Zr magnesium alloy with 4.2%Y

2.7%Nd

0.1%（La+Ce）

and 0.5%Zr reaches 223 MPa

presenting desirable mechanical properties. In addition

the average corrosion rate of the alloy is 0.209 mg/（cm~2·h） in Hank’s solution for 96 hours.
