| 摘 要： | 采用电化学测量、扫描电镜观察、X射线衍射和X射线光电子能谱分析对消失模铸造和金属型铸造Mg-11Gd-3Y镁合金的腐蚀行为的影响进行研究.由于冷却速度的差异使得消失模铸造Mg-11Gd-3Y镁合金的Mg24(Gd,Y)5相数量明显比金属型铸造Mg-11Gd-3Y镁合金的少,其固溶于基体中的合金化元素明显高于金属型铸造M...

| Abstract: | The influences of two kinds of casting modules of metal casting (MC) and expandable pattern casting (EPC) on the corrosion behavior of Mg-11Gd-3Y alloy were studied by electrochemical measurements, scanning electron microscopy (SEM) observation, X-ray diffractometry (XRD) and X-ray photoelectron spectroscopy (XPS) analysis. It is found that the quantity of the Mg 24 (Gd, Y) 5 phase in MC is more than that in EPC due to the cooling rate. There is more alloying element dissolved in the matrix compared with MC... |
