采用X射线衍射（XRD）、扫描电子显微镜（SEM）、失重腐蚀速率、腐蚀残余强度（CRS）和慢应变速率拉伸（SSRT）等测试方法，研究了稀土Er对AM50镁合金动态腐蚀力学性能的影响。结果表明，Er的加入使合金中出现了Al3Er新相，组织得到细化。稀土Er对合金耐蚀性的影响顺序为0.5% > 1.5% > 1.0% > 0. 432 h腐蚀速率降低。168 h内的CRS结果表明，掺Er量为0.5%时强度最高，衰减率最小。从CRS拉伸曲线的形状和拉伸断口的形貌来看，稀土Er的加入并没有改变CRS合金的断口形貌，其断口仍为准解理。
The X-ray diffraction (XRD), scanning electron microscope (SEM), weight loss corrosion rate, corrosion residual strength (CRS), and slow strain rate tensile (SSRT) methods were used to study the effects of the addition of rare earth Erbium (Er) on the dynamic corrosion mechanical properties of the AM50 magnesium alloy. The results show that after Er was added, a new phase of Al3Er appeared and the microstructure was refined. The corrosion resistance of rare earth Er addition to the alloy was 0.5% > 1.5% > 1.0% > 0. Furthermore, the corrosion rates decreased in 432 h. The CRS results within 168 h show that the strength after an addition of 0.5% Er was the highest and the decline rate was the smallest. According to the shape of the tensile curve of CRS and the morphology of the tensile fracture, the addition of rare earth Er did not change the fracture form of the alloy, which remained as quasi-cleavage.
