| Abstract: | The corrosion behavior of Mg-14Li-lAl-0.1Ce in sodium halide KaX(X=F,Cl,Br and I) solutions was investigated by immersion test and electrochemical methods.Its corrosion rate in various solutions was accessed by mass loss method.The phase constituent.chemical composition and morphologies of corroded surface after 48 h immersed in different solutions were characterized by X-ray diffraction(XRD) and scanning electron microscopy(SEM).The results revealed that the corrosion resistance of Mg-14Li-lAl-0.1Ce in sod... |
