Abstract

Liquid cell transmission electron microscopy (LCTEM) was developed for analyzing the liquid-phase samples and shows not only the in-situ morphological images of the sample, but also the in-situ material information such as selected area diffraction (SAD) and energy-dispersive X-ray spectroscopy (EDS). The researchers analyzed the corrosion behavior of Mg-Zn-Ca alloys using both polarization and immersion tests. However, these methods only provide macro scale corrosion characteristics. In this study, the corrosion behavior of the Mg-Zn-Ca alloy powders was analyzed using LCTEM. It provided the in-situ sub-micron scale images and time-dependent composition, thereby revealing evidence of selective corrosion of the α-Mg phase as well as the IM1 phase (Ca2Mg6Zn3).
